[Lustre-devel] [wc-discuss] [Twg] Lustre and cross-platform portability

[Alexey Lyashkov]

Trust me.
I (with two friends) write  a FUSE client for a FreeBSD in past.
Most issues related to a porting libcfs/libsysio to FreeBSD, but anyway patch isn''t huge ~200kb.
I have plan to send that patch in near time, as 2.3 landing window open.
