From 5d8943b04bab62614559f308b4e39533ca7f8e08 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 3 Aug 2013 12:09:34 +0400 Subject: afs: get rid of redundant ->d_name.len checks No dentry can get to directory modification methods without having passed either ->lookup() or ->atomic_open(); if name is rejected by those two (or by ->d_hash()) with an error, it won't be seen by anything else.
