[Ocfs2-devel] [PATCH 0/3] POSIX ACL config and mount option changes

[Jan Kara]

  Hi,

  we've discussed with Joel and Mark how to improve user experience
with ACL mount options. In the end we'va agreed on the following:

 1) Rip out CONFIG_OCFS2_POSIX_ACL.  The code is always built in.
 2) Always enable acls if a filesystem has xattrs.  This is a noop if no
    one ever calls setacl.
 3) If a user explicitly puts -oacl on the mount command line, but the
    filesystem doesn't have xattrs, fail the mount.  This is a safe place
    to catch people changing kernels, as a too-old kernel driver likely
    doesn't have xattrs anyway.
 4) If a user explicitly puts -onoacl on the mount command line, they get

  This patch series implements the changes. The last patch also fixes
a bug when acls are enabled only on remount.
