  33         <command>vfs_linux_xfs_sgid</command> is a VFS module to work around an
  34         old Linux XFS bug fixed in 3.11: the SGID bit is not inherited during mkdir
  35         when a default ACL is set

  40         The <command>vfs_linux_xfs_sgid</command> VFS module will work around this
  41         bug by manually setting the SGID bit after a <command>mkdir</command>
  42         if the parent directory had the SGID bit set.
