They probably can.

Note, though, that we still have a problem with NTFS or NFSv4 acls:
unlike POSIX acls, those permit you to give a particular user execute
rights without having an execute mode bit set.

If we want to allow Linux to support that type of ACL, then we will in
fact need to move the mode bit check down into the filesystems, and
remove the VFS override.
The patches that I sent in have shied short of doing this (they only
remove the existing inconsistency within the VFS) but I'd be happy to
write something up if Al is willing to consider it.
