From 5707c87f20bca9e76969bb4096149de6ef74cbb9 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 2 Mar 2012 14:47:15 -0800 Subject: [PATCH] vfs: clarify and clean up dentry_cmp() It did some odd things for unclear reasons. As this is one of the functions that gets changed when doing word-at-a-time compares, this is yet another of the "don't change any semantics, but clean things up so that subsequent patches don't get obscured by the cleanups".
