Hi Jens-- I have a few last patches for bcache targeting 4.15 if it's possible to get them in. I'm sorry this is a bit late.
All are reviewed and have received a moderate amount of test in my environment (and I'm continuing testing). [PATCH 1/5] bcache: only permit to recovery read error when cache [PATCH 2/5] bcache: convert cached_dev.count from atomic_t to [PATCH 3/5] bcache: update bucket_in_use in real time [PATCH 4/5] bcache: fix wrong cache_misses statistics [PATCH 5/5] bcache: explicitly destroy mutex while exiting Patches 1 and 3 are critical. The first fixes correctness problems if a cache volume fails and is being carried in distro trees. #3 prevents a rare issue that can cause extended hanging of end-user I/O. The other three patches are relatively safe cleanup. Thanks-- Mike
