From 69dd3b3930f96b624228000921f417fb0919a6ab Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 25 Aug 2022 09:31:05 -0400 Subject: libceph: add CEPH_OSD_OP_ASSERT_VER support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ...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.
