Subject: os/ObjectMap: add get_db() accessor
X-Git-Tag: v12.2.13~172^2~1
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=32ffd5380b72c26bbb7d2b35c91e7a4111e5b54b;p=ceph.git

os/ObjectMap: add get_db() accessor

This is just to let us get at the underlying KeyValueDB for DBObjectMap.
It is not really better or worse than adding accessors for things like
GetEstimatedSize() to ObjectMap.
