4e34e719e4 fs: take the ACL checks to common code
Replace the ->check_acl method with a ->get_acl method that simply reads an
ACL from disk after having a cache miss.  This means we can replace the ACL
checking boilerplate code with a single implementation in namei.c.

e6aabe0cac ocfs2: Always include ACL support
To become consistent with filesystems such as XFS or BTRFS, make posix
ACLs always available. This also reduces possibility of
misconfiguration on admin's side.

929fb014e0 ocfs2: add POSIX ACL API
This patch adds POSIX ACL(access control lists) APIs in ocfs2. We convert
struct posix_acl to many ocfs2_acl_entry and regard them as an extended
attribute entry.
