Subject[PATCH 17/20] staging: lustre: llite: allow cached acls
Date
From: Dmitry Eremin <dmitry.eremin@intel.com>

Move the freeing of all cached acls from ll_get_acl() to the
function ll_clear_inode(). This way we free all cached acls
for the inode just before clearing it. This allow us to take
advantage of cached acls and correctly free them before free.
