From a1ea787c7b6ec036d169d84e08cca7b6e399ba70 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 23 Feb 2010 14:02:44 -0800 Subject: [PATCH] ceph: fix client_request_forward decoding The tid is in the message header, not body. Broken since 6df058c0. No need to look at next mds session; just mark the request and be done. (The old error path was broken too, but now it's gone.)
