the patch looks 99% percent good to me :-)
I am not sure if I am overly paranoid here, but I would add a check for
zfsvfs->z_shares_dir being non-zero before comparing anything with it.
I am also not sure if doing actual zfs_zget only to check zp_gen != fid_gen or
z_unlinked is required. Probably not.
could you please test Rick's patch?
