Subject: ReplicatedPG::submit_log_entries: fill in repop->v
X-Git-Tag: v11.1.0~58^2~5
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=ef376c9793ea76165722d8929b700b236e78bdba;p=ceph.git

ReplicatedPG::submit_log_entries: fill in repop->v

This way, we can deal with waiting_for_commit appropriately.
Also, add more debugging to new_repop and already_*.
