From 844d87c3329980e2b1849cf53205d7fa965d8995 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 5 Feb 2013 13:40:09 -0800 Subject: ceph: do not assume r_old_dentry[_dir] always set together Do not assume that r_old_dentry implies that r_old_dentry_dir is also true. Separate out the ref cleanup and make the debugs dump behave when it is NULL.
