From d79698da32b317e96216236f265a9b72b78ae568 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 26 Jul 2011 11:31:26 -0700 Subject: ceph: document unlocked d_parent accesses For the most part we don't care about racing with rename when directing MDS requests; either the old or new parent is fine. Document that, and do some minor cleanup.
