However, the switch for ufs_pathconf(= )=20 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= hat=20 what they mean by XATTR is what we mean by extended attribute. However, I= =20 think that's a confusion fairly specific to Solaris and that we do have and= =20 apply a consistent meaning for extended attribute. A question for Pawel wo= uld=20 be how he plans to expose ZFS "extended attributes" (file streams) in FreeB= SD,=20 so I've CC'd him.
