.Snapshot-based mirroring process no longer gets cancelled
Previously, as a result of an internal race condition, the `rbd mirror snapshot schedule add` command would be cancelled out. The snapshot-based mirroring process for the affected image would not start, if no other existing schedules were applicable.
With this release, the race condition is fixed and the snapshot-based mirroring process starts as expected.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.

Chris, can you take a look? It seems there are a number of rbd-mirror crashes with this backtrace: "assert_msg": "/builddir/build/BUILD/ceph-16.2.7/src/librbd/ImageWatcher.cc: In function 'void librbd::ImageWatcher<ImageCtxT>::schedule_request_lock(bool, int) [with ImageCtxT = librbd::ImageCtx]' thread 7f6ccc123700 time 2022-03-26T15:39:31.399999+0000\n/builddir/build/BUILD/ceph-16.2.7/src/librbd/ImageWatcher.cc: 580: FAILED ceph_assert(m_image_ctx.exclusive_lock && !m_image_ctx.exclusive_lock->is_lock_owner())\n", "assert_thread_name": "io_context_pool", "backtrace": [ "/lib64/libpthread.so.0(+0x12c20) [0x7f6ce068ac20]", "gsignal()", "abort()", "(ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x1a9) [0x7f6ce124ad4f]", "/usr/lib64/ceph/libceph-common.so.2(+0x276f18) [0x7f6ce124af18]", "(librbd::ImageWatcher<librbd::ImageCtx>::schedule_request_lock(bool, int)+0x3b6) [0x5617d288a596]", "(librbd::ImageWatcher<librbd::ImageCtx>::handle_request_lock(int)+0x486) [0x5617d288aae6]", "(librbd::image_watcher::NotifyLockOwner::finish(int)+0x2b) [0x5617d2a0f25b]", "(librbd::image_watcher::NotifyLockOwner::handle_notify(int)+0x9e4) [0x5617d2a10014]", "(Context::complete(int)+0xd) [0x5617d26e080d]", "(boost::asio::detail::completion_handler<boost::asio::detail::work_dispatcher<librbd::asio::ContextWQ::queue(Context*, int)::{lambda()#1}> >::do_complete(void*, boost::asio::detail::scheduler_operation*, boost::system::error_code const&, unsigned long)+0x66) [0x5617d26e0ca6]", "(boost::asio::detail::strand_service::do_complete(void*, boost::asio::detail::scheduler_operation*, boost::system::error_code const&, unsigned long)+0x85) [0x5617d2854435]", "/lib64/librados.so.2(+0xc12e2) [0x7f6cea87e2e2]", "/lib64/librados.so.2(+0xc6cea) [0x7f6cea883cea]", "/lib64/libstdc++.so.6(+0xc2ba3) [0x7f6cdf499ba3]", "/lib64/libpthread.so.0(+0x817a) [0x7f6ce068017a]", "clone()" ],
