I think it sounds fairly reasonable. However, the switch for ufs_pathconf(=

appears to be missing the _PC_XATTR_EXISTS case?

I'd probably panic rather than KASSERT() there.

I'll also need to update the fpathconf(2) man page to list _PC_XATTR_*.

Finally, I'm not convinced, having reread the fsattr man page on Solaris, t=

what they mean by XATTR is what we mean by extended attribute. However, I=

think that's a confusion fairly specific to Solaris and that we do have and=

be how he plans to expose ZFS "extended attributes" (file streams) in FreeB=

so I've CC'd him.
