Subject: os/bluestore: keep onode refs for lifetime of obc
X-Git-Tag: v12.0.1~12^2~29
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=9b28d615e77f002a38ac84458bd7fb1acac4d86d;p=ceph.git

os/bluestore: keep onode refs for lifetime of obc

This ensures that we don't trim an onode from the cache while it has a
txc that is still in flight.  Which in turn ensures that if we try to read
the object, we will have any writing buffers available.
