VFS: Make link_path_walk set LOOKUP_CONTINUE before calling permission().
This will allow nfs_permission() to perform additional optimizations when walking the path, by folding the ACCESS(MAY_EXEC) call on the directory into the lookup revalidation. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
