OK; here's a summary of what I found so far, now running: FreeBSD g1-227.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #0 233772M:= Mon Apr 2 05:42:48 PDT 2012 root@g1-227.catwhisker.org:/usr/obj/usr/s= rc/sys/CANARY i386 * First, the patch applied cleanly (via "patch -p1"). * Resulting sources build with no issues. * Prior specification I had in /etc/fstab: tmpfs /tmp tmpfs rw,size=3D2147483648 0 0 worked same as before the patch; "df -h /tmp" reported a size of 2.0G. * Changing the above to read: tmpfs /tmp tmpfs rw,size=3D2g 0 0 also provided the same result, so the unit-specification code looks as if it's working as expected. * I have 20G specified for swap, and 4G RAM (and, as above, I'm running i386). Changing the above tmpfs line in /etc/fstab to tmpfs /tmp tmpfs rw,size=3D8g 0 0 (still) yields: g1-227(10.0-C)[3] df -h /tmp Filesystem Size Used Avail Capacity Mounted on tmpfs 23G 12k 23G 0% /tmp g1-227(10.0-C)[4]=20 (Yes, I'm using a whopping total of 12kB while running X. I know of *very* few folks who use the window manager I prefer. :-}) I'll try exercising it a bit during the day at work & report anything noteworthy. But so far, I see no evidence of regression, and there is some measure of usability improvement (IMO). So it's looking encouraging. :-) Peace, david --=20 David H.
