Subject: osd/ReplicatedPG: drop RepGather::ondone callback
X-Git-Tag: v0.75~45^2~7
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=923bff1dba11b0bb7d0d8f7b0cdec8c0064825b8;p=ceph.git

osd/ReplicatedPG: drop RepGather::ondone callback

We kick the blocked contexts in the completion path of process_copy_chunk(),
after we have take the RWWRITE obc lock.  There is no need to delay the
unblocking until the RepGather finishes.

This also fixes a leak: the ondone wasn't getting cleaned up if a peering
interval change happens and the repgather is applied early in on_change().
