From 48293699a09324d2e3c66bd53d10eed6d67937a0 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 24 May 2011 13:06:04 -0700 Subject: vfs: dentry_unhash immediately prior to rmdir This presumes that there is no reason to unhash a dentry if we fail because it is a mountpoint or the LSM check fails, and that the LSM checks do not depend on the dentry being unhashed.
