X-Git-Tag: v0.92~99^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=59b70fe20b00400f6152debb3d302ca3bc75d31b;p=ceph.git

Cleanup: Drop hobject_incorrect_pool

This field in MOSDSubOp, used to support very old version
OSD(MOSDSubOp header version < 7, which was introduced in
mid 2012 by commit 2fe9816305fc1406ab7fb043bbb32affffc2d190)

Now since two years pasted, we don't need it anymore.
