In fact, it is used so often that I would be mightily nervous bloating it with another argument. The current implementation works reasonably well for the most common use of O_DIRECT I/O, where generally certain portions of a file will always be accessed O_DIRECT while other portions will always be accessed without O_DIRECT. For example, when accessing a large database you may wish to allow the OS to cache management structures like embedded hash tables, but do your own caching of the (possibly terrabytes) of data in order to make the most efficient use of the cpu by avoiding unexpected blockages. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message From owner-freebsd-fs Sat Jan 5 10:47: 9 2002 Delivered-To: freebsd-fs@freebsd.org Received: from carbon.btinternet.com (carbon.btinternet.com [194.73.73.92]) by hub.freebsd.org (Postfix) with ESMTP id F173E37B41A; Sat, 5 Jan 2002 10:45:31 -0800 (PST) Received: from host213-123-134-22.in-addr.btopenworld.com ([213.123.134.22] helo=dvsgroup) by carbon.btinternet.com with esmtp (Exim 3.22 #8) id 16MvnT-0003k1-00; Sat, 05 Jan 2002 18:43:59 +0000 Received: from Spooler by dvsgroup (Mercury/32 v3.01a) ID MO005490; 5 Jan 02 18:42:38 -0000 Received: from spooler by dvsgroup (Mercury/32 v3.01a); 5 Jan 02 18:42:10 -0000 Received: from user (4.48.5.139) by dvsgroup (Mercury/32 v3.01a) ID MG005487; 5 Jan 02 18:41:08 -0000 From: smr1tks@oa.sharp.co.jp To: Subject: Five Dollar Reports Date: Sat, 05 Jan 2002 12:00:49 -0600 X-Priority: 3 X-MSMail-Priority: Normal Message-ID: <11BC4AF14ECC@dvsgroup> Sender: owner-freebsd-fs@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Dear Friend: AS SEEN ON NATIONAL TV: ''Making over half million dollars every 4 to 5 months from your home for an investment of only $25 U.S. Dollars expense one time'' THANKS TO THE COMPUTER AGE AND THE INTERNET! Before you say ''Bull'', please read the following. This is the letter you have been hearing about on the news lately. Due to the popularity of this letter on the Internet, a national weekly news program recently devoted an entire show to the investigation of this program described below, to see if it really can make people money. The show also investigated whether or not the program was legal. Their findings proved once and for all that there are ''absolutely NO Laws prohibiting the participation in the program and if people can follow the simple instructions, they are bound to make some mega bucks with only $25 out of pocket cost''. DUE TO THE RECENT INCREASE OF POPULARITY & RESPECT THIS PROGRAM HAS ATTAINED, IT IS CURRENTLY WORKING BETTER THAN EVER. This is what one had to say: ''Thanks to this profitable opportunity. I was approached many times before but each time I passed on it. I am so glad I finally joined just to see what one could expect in return for the minimal effort and money required. To my astonishment, I received total $ 610,470.00 in21 weeks, with money still coming in''. Pam Hedland, Fort Lee, New Jersey. ------------------------------------------------------------------------- Here is another testimonial: 'This program has been around for a long time but I never believed in it, but one day when I received this again in the mail I decided to gamble my $25 on it. I followed the simple instructions and walaa ..... 3 weeks later the money started to come in. First month I only made $240.00 but the next 2 months after that I made a total of $290,000.00. So far, in the past 8 months by re-entering the program, I have made over $710,000.00 and I am playing it again. The key to success in this program is to follow the simple steps and NOTchange anything.'' More testimonials later but first, *** PRINT THIS NOW FOR YOUR FUTURE REFERENCE *** $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ If you would like to make at least $500,000 every 4 to 5 months easily and comfortably, please read the following...THEN READ IT AGAIN and AGAIN!!! $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ FOLLOW THE SIMPLE INSTRUCTION BELOW AND YOUR FINANCIAL DREAMS WILL COME TRUE, GUARANTEED! INSTRUCTIONS: **** Order all 5 reports shown on the list below. **** For each report, send $5CASH, THE NAME & NUMBER OF THE REPORT YOU ARE ORDERING and YOUR E-MAIL ADDRESS to the person whose name appears ON THAT LIST next to the report.

IMPORTANT -DO NOT alter the names of the people who are listed next to each report, or their sequence on the list, in any way other than what is instructed below in step '' 1 through 6 '' or you will loose out on majority of your profits. Once you understand the way this works, you will also see how it does not work if you change it. Remember, this method has been tested, and if you alter, it will NOT work!!! People have tried to put their friends/relatives names on all five thinking they could get all the money. But it does not work this way. Believe us, we all have tried to be greedy and then nothing happened. So Do Not try to change anything other than what is instructed. Because if you do, it will not work for you. Remember, honesty reaps the reward!!! 1.. After you have ordered all 5 reports, take this advertisement and REMOVE the name & address of the person in REPORT # 5. This person has made it through the cycle and is no doubt counting their fortune. 2.... Move the name & address in REPORT #4down TO REPORT #5. 3.... Move the name & address in REPORT #3 down TO REPORT #4. 4.... Move the name & address in REPORT #2 down TO REPORT #3. 5.... Move the name & address in REPORT #1 down TO REPORT #2 6.... Insert YOUR name & address in the REPORT #1 Position.

DO NOT MAKE ANY OTHER CHANGES. Save this on a disk as well just in case if you loose any data. To assist you with marketing your business on the Internet, the 5 reports you purchase will provide you with invaluable marketing information which includes how to send bulk e-mails legally, where to find thousands of free classified ads and much more. There are 2 Primary methods to get this venture going: METHOD # 1 : BY SENDING BULK E-MAIL LEGALLY ============================================ let's say that you decide to start small, just to see how it goes, and we will assume You and those involved send out only 5,000 e-mails each. Let's also assume that the mailing receive only a 0.2% response (the response could be much better but lets just say it is only 0.2% . Also many people will send out hundreds of thousands e-mails instead of only 5,000 each). Continuing with this example, you send out only 5,000 e-mails. With a 0.2%response, that is only 10 orders for report #1. Those 10people responded by sending out 5,000 e-mail each for a total of 50,000. Out of those 50,000 e-mails only 0.2% responded with orders. That's = 100 people responded and ordered Report #2. Those 100 people mail out 5,000 e-mails each for a total of 500,000 e-mails. The 0.2% response to that is 1000 orders for Report #3. Those 1000 people send out 5,000 e-mails each for a total of 5 million e-mails sent out. The 0.2% response to that is 10,000 orders for Report #4. Those 10,000 people send out 5,000 e-mails each for a total of 50,000,000 (50 million)e-mails. The 0.2% response to that is 100,000 orders for Report # 5. THAT'S 100,000 ORDERS TIMES $5 EACH = $500,000.00 (half million). Your total income in this example is: 1..... $50+ 2..... $500+ 3..... $5,000+ 4..... $50,000+ 5..... $500,000.........Grand Total = $555,550.00 NUMBERS DO NOT LIE. GET A PENCIL & PAPER AND FIGURE OUT THE WORST POSSIBLE RESPONSES AND NO MATTER HOW YOU CALCULATE IT, YOU WILL STILL MAKE A LOT OF MONEY! ------------------------------------------------------------------------ REMEMBER FRIEND, THIS IS ASSUMING ONLY 10 PEOPLE ORDERING OUT OF 5,000 YOU MAILED TO. Dare to think for a moment what would happen if everyone, or half or even one 4thof those people mailed 100,000 e-mails each or more? There are over 150 million people on the Internet worldwide and counting. Believe me, many people will do just that, and more! METHOD #2 : BY PLACING FREE ADS ON THE INTERNET =================================================== Advertising on the net is very very inexpensive and there are hundreds of FREE places to advertise. Placing a lot of free ads on the Internet will easily get a larger response. We strongly suggest you start with Method # 1 and add METHOD #2 as you go along. for every $5 you receive, all you must do is e-mail them the Report they ordered. That's it. Always provide same day service on all orders. This will guarantee that the e-mail they send out, with your name and address on it, will be prompt because they can not advertise until they receive the report. AVAILABLE REPORTS ORDER EACH REPORT BY ITS NUMBER & NAME ONLY. Notes: Always send $5 cash (U.S. CURRENCY) for each Report. Checks NOT accepted. Make sure the cash is concealed by wrapping it in at least 2 sheets of paper. On one of those sheets of paper, Write the NUMBER & the NAME of the Report you are ordering, YOUR E-MAIL ADDRESS and your name and postal address.

After you have received 10 orders, 2 to 3 weeks after that you should receive 100 orders or more for REPORT #2. If you did not, continue advertising or sending e-mails until you do. Once you have received 100 or more orders for Report #2, YOU CAN RELAX, because the system is already working for you , and the cash will continue to roll in! THIS IS IMPORTANT TO REMEMBER: Every time your name is moved down on the list, you are placed in front of a different report. You can KEEP Track of your PROGRESS by watching which report people are ordering from you. IF YOU WANT TO GENERATE MORE INCOME SEND ANOTHER BATCH OF E-MAIL SAND START THE WHOLE PROCESS AGAIN.

IT IS UP TO YOU NOW! ************** MORETESTIMONIALS**************** ' My name is Mitchell. My wife, Jody and I live in Chicago. I am an accountant with a major U.S. Corporation and I make pretty good money. When I received this program I grumbled to Jody about receiving ''junk mail''. I made fun of the whole thing, spouting my knowledge of the population and percentages involved. I ''knew'' it wouldn't work. Jody totally ignored my supposed intelligence and few days later she jumped in with both feet. I made merciless fun of her, and was ready to lay the old ''I told you so'' on her when the thing didn't work. Well, the laugh was on me! Within 3 weeks she had received 50 responses. Within the next 45 days she had received a total of $ 147,200.00 all cash!I was shocked. I have joined Jody in her ''hobby''. Mitchell Wolf, M.D. , Chicago, Illinois ------------------------------------------------------------------------- Not being the gambling type, it took me several weeks to make up my mind to participate in this plan. But conservative that I am, I decided that the initial investment was so little that there was just no way that I wouldn't get enough orders to at least get my money back. I was surprised when I found my medium size post office box crammed with orders. I made $319,210.00 in the first 12 weeks. The nice thing about this deal is that it does not matter where people live. There simply isn't a better investment with a faster return and so big''. Dan Sondstrom, Alberta, Canada ------------------------------------------------------------------------- 'I had received this program before. I deleted it, but later I wondered if I should have given it a try. Of course, I had no idea who to contact to get another copy, so I had to wait until I was e- mailed again by someone else.........11 months passed then it luckily came again...... I did not delete this one! I made more than $490,000 on my first try and all the money came within 22 weeks''. Susan De Suza, New York, N.Y. ----------------------------------------------------------------------- '' It really is a great opportunity to make relatively easy money with little cost to you. I followed the simple instructions and within 10 days the money started to come in. My first month I made $ 20, 560.00 and by the end of third month my total cash count was $ 362,840.00.
