-Subject: posix_acl: handle NULL ACL in posix_acl_equiv_mode
-
-Various filesystems don't bother checking for a NULL ACL in
-posix_acl_equiv_mode, and thus can dereference a NULL pointer when it
-gets passed one. This usually happens from the NFS server, as the ACL tools
-never pass a NULL ACL, but instead of one representing the mode bits.
-
-Instead of adding boilerplat to all filesystems put this check into one place,
-which will allow us to remove the check from other filesystems as well later
-on.
