From 513a8243d67f8e8d27f2883bd2f18bc87c7ca376 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Tue, 13 May 2014 11:19:26 +0400 Subject: libceph: mon_get_version request infrastructure Add support for mon_get_version requests to libceph. This reuses much of the ceph_mon_generic_request infrastructure, with one exception. Older OSDs don't set mon_get_version reply hdr->tid even if the original request had a non-zero tid, which makes it impossible to lookup ceph_mon_generic_request contexts by tid in get_generic_reply() for such replies. As a workaround, we allocate a reply message on the reply path. This can probably interfere with revoke, but I don't see a better way.
