This ensures the caller knows exactly what the memory lifetime of this returned object is. This makes the NFSv4 ACL code consistent with the POSIX and NT ACL code, to avoid supprising developers who have worked on those other parts of the ACL code. Most of this patch is adding a memory context to the callers and passing it in. Andrew Bartlett Reviewed-by: Jeremy Allison <jra@samba.org>
