If you really are willing to help port a FS to FreeBSD, you could help with the XFS port. :-) It is a bit stalled at the moment as I'm busy doing work that generates income, but I do get a chance to bang on it once in a while ... hopefully I will be able to mount a FS soon. Note to quickly answer one of your questions, yes some modifications will be need to the core kernel code to support pinning, but I suspect is will be very minor due to support for softupdates. Ohh and porting a linux FS to BSD is much more difficult than porting a IRIX FS to BSD, linux has a different IO layering concept than other unix systems. m p wrote: >Hi, > >let it be technical again. > >I wanted to do a little bit more research before >bringing up the idea of porting the GPLed version of >JFS to *BSD.
