[PATCH] fix nfsacl pointer arithmetic and pg_class initialization bugs
* Pointer arithmetic bug: p is in word units. This fixes a memory corruption with big acls. * Initialize pg_class to prevent a NULL pointer access. Signed-off-by: Andreas Gruenbacher <agruen@suse.de> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
