[lustre-devel] [PATCH 147/151] lustre: introduce CONFIG_LUSTRE_FS_POSIX_ACL

From: NeilBrown <neilb at suse.com>
Lustre (or any file system) should not conditionally
compile code based on CONFIG_FS_POSIX_ACL. This config
option enables library support.
A file system can define it's own config option,
which then selects CONFIG_FS_POSIX_ACL (if needed). It should
act on its own option, not the library one.
This patch makes that change.
