   4 Subject: ufs: fix braino in ufs_get_inode_gid() for solaris UFS flavour
   5
   6 [ Upstream commit 4e9036042fedaffcd868d7f7aa948756c48c637d ]
   7
   8 To choose whether to pick the GID from the old (16bit) or new (32bit)
   9 field, we should check if the old gid field is set to 0xffff.  Mainline
  10 checks the old *UID* field instead - cut'n'paste from the corresponding
  11 code in ufs_get_inode_uid().
