From e4eaac06bcccb2a70bca6a2de9871882dce2aa14 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 24 May 2011 13:06:07 -0700 Subject: [PATCH] vfs: push dentry_unhash on rename_dir into file systems Only a few file systems need this. Start by pushing it down into each rename method (except gfs2 and xfs) so that it can be dealt with on a per-fs basis.
