[Linux PATCH] fcntl: add new F_OFD_*32 constants and handle them appropriately

[Christoph Hellwig]

NAK.  People should stop using 32-bit off_t and friends yesterday.
It's a shame that glibc hasn't cought up with last century yet and
stopped providing the non-LFS APIs for newly compiled code, but 
we certainly should not bloat the kernel for the idiotic behavior.

In addition anyone is going to use a new Linux-only feature like the
OFS locks should be using LFS support anyway.
