Subject: ceph: cleanup aborted requests when re-sending requests.
X-Git-Tag: v3.12.7~151
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5bb822258878721ca995a7015c6e076cc96be849;p=kernel%2Fkernel-generic.git

ceph: cleanup aborted requests when re-sending requests.

commit eb1b8af33c2e42a9a57fc0a7588f4a7b255d2e79 upstream.

Aborted requests usually get cleared when the reply is received.
If MDS crashes, no reply will be received. So we need to cleanup
aborted requests when re-sending requests.
