Merge tag 'for-5.5/block-20191121' of git://git.kernel.dk/linux-block
Pull core block updates from Jens Axboe: "Due to more granular branches, this one is small and will be followed with other core branches that add specific features. I meant to just have a core and drivers branch, but external dependencies we ended up adding a few more that are also core. The changes are: - Fixes and improvements for the zoned device support (Ajay, Damien) - sed-opal table writing and datastore UID (Revanth) - blk-cgroup (and bfq) blk-cgroup stat fixes (Tejun) - Improvements to the block stats tracking (Pavel) - Fix for overruning sysfs buffer for large number of CPUs (Ming) - Optimization for small IO (Ming, Christoph) - Fix typo in RWH lifetime hint (Eugene) - Dead code removal and documentation (Bart) - Reduction in memory usage for queue and tag set (Bart) - Kerneldoc header documentation (André) - Device/partition revalidation fixes (Jan) - Stats tracking for flush requests (Konstantin) - Various other little fixes here and there (et al)" * tag 'for-5.5/block-20191121' of git://git.kernel.dk/linux-block: (48 commits) Revert "block: split bio if the only bvec's length is > SZ_4K" block: add iostat counters for flush requests block,bfq: Skip tracing hooks if possible block: sed-opal: Introduce SUM_SET_LIST parameter and append it using 'add_token_u64' blk-cgroup: cgroup_rstat_updated() shouldn't be called on cgroup1 block: Don't disable interrupts in trigger_softirq() sbitmap: Delete sbitmap_any_bit_clear() blk-mq: Delete blk_mq_has_free_tags() and blk_mq_can_queue() block: split bio if the only bvec's length is > SZ_4K block: still try to split bio if the bvec crosses pages blk-cgroup: separate out blkg_rwstat under CONFIG_BLK_CGROUP_RWSTAT blk-cgroup: reimplement basic IO stats using cgroup rstat blk-cgroup: remove now unused blkg_print_stat_{bytes|ios}_recursive() blk-throtl: stop using blkg->stat_bytes and ->stat_ios bfq-iosched: stop using blkg->stat_bytes and ->stat_ios bfq-iosched: relocate bfqg_*rwstat*() helpers block: add zone open, close and finish ioctl support block: add zone open, close and finish operations block: Simplify REQ_OP_ZONE_RESET_ALL handling block: Remove REQ_OP_ZONE_RESET plugging ...
