From 3637c05d881b2b7bab36f339245b8963f5b29c9f Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Mon, 26 Mar 2012 12:54:20 +0200 Subject: [PATCH] vfs: don't revalidate just looked up dentry __lookup_hash() calls ->lookup() if the dentry needs lookup and on success revalidates the dentry (all under dir->i_mutex). While this is harmless it doesn't make a lot of sense.
