Subject: [PATCH v12 34/54] libceph: add CEPH_OSD_OP_ASSERT_VER support
Date: Thu, 31 Mar 2022 11:31:10 -0400 [thread overview]
Message-ID: <20220331153130.41287-35-jlayton@kernel.org> (raw)
In-Reply-To: <20220331153130.41287-1-jlayton@kernel.org>
...and record the user_version in the reply in a new field in
ceph_osd_request, so we can populate the assert_ver appropriately.
Shuffle the fields a bit too so that the new field fits in an
existing hole on x86_64.
