Merge window most likely opens on Monday. Fixes, improvements, hilights: * improved global reserve utilization * speedup dead root detection during orphan cleanup * send: emit file capabilities after chown * direct io port to iomap infrastructure Cleanups: * backref iterators factored out, used for normal backrefs and relocation * direct io simplified and cleaned up * block group reading * set/get helpers * REF_COWS renamed to SHAREABLE Merge outlook ------------- >From now on only selected fixes will be merged to 5.8 queue. In 5.9 I'd like to do a stabilization release, we've had quite some core updates in 5.7. So, merge less intrusive features (ioctls, sysfs updates, ...) and reasonable cleanups, besides the usual fixes. I have looked at the following patchsets and think that we should be able to finalize them in time: * device mirror balancing - besides the manual mirror selection we need a better default balancing policy and may need to experiment a bit to find replacement for the pid-based one * ioctl to dump chunks - to replace search tree ioctl where possible, eg. df or usage, (also this might be used as a heuristic for balancing or to suggest what to balance but that would be a bonus) The authenticated checksums patchset is on a good track, the core is done but as this is a security-related feature we don't want to rush it.
