Mike ---------------------------------------------------------------- - Various DM persistent-data library improvements and fixes that benefit both the DM thinp and cache targets. - A few small DM kcopyd efficiency improvements. - Significant zoned related block core, DM core and DM zoned target changes that culminate with adding zoned append emulation (which is required to properly fix DM crypt's zoned support). - Various DM writecache target changes that improve efficiency. Adds an optional "metadata_only" feature that only promotes bios flagged with REQ_META. But the most significant improvement is writecache's ability to pause writeback, for a confiurable time, if/when the working set is larger than the cache (and the cache is full) -- this ensures performance is no worse than the slower origin device. ---------------------------------------------------------------- Baokun Li (1): dm writecache: use list_move instead of list_del/list_add in writecache_writeback() Colin Ian King (1): dm ps io affinity: remove redundant continue statement Damien Le Moal (13): dm zoned: check zone capacity dm: Fix dm_accept_partial_bio() relative to zone management commands dm: cleanup device_area_is_invalid() dm: move zone related code to dm-zone.c dm: Introduce dm_report_zones() dm: Forbid requeue of writes to zones block: improve handling of all zones reset operation block: introduce bio zone helpers block: introduce BIO_ZONE_WRITE_LOCKED bio flag dm: rearrange core declarations for extended use from dm-zone.c dm: introduce zone append emulation dm crypt: Fix zoned block device support dm zone: fix dm_revalidate_zones() memory allocation Hou Tao (1): dm btree remove: assign new_root only when removal succeeds Joe Thornber (4): dm btree: improve btree residency dm space maps: don't reset space map allocation cursor when committing dm space maps: improve performance with inc/dec on ranges of blocks dm space map disk: cache a small number of index entries Mike Snitzer (2): dm writecache: add "cleaner" and "max_age" to Documentation dm io tracker: factor out IO tracker Mikulas Patocka (12): dm kcopyd: avoid useless atomic operations dm kcopyd: avoid spin_lock_irqsave from process context dm writecache: don't split bios when overwriting contiguous cache content dm writecache: interrupt writeback if suspended dm writecache: remove unused gfp_t argument from wc_add_block() dm writecache: commit just one block, not a full page dm writecache: have ssd writeback wait if the kcopyd workqueue is busy dm writecache: flush origin device when writing and cache is full dm writecache: write at least 4k when committing dm writecache: add optional "metadata_only" parameter dm writecache: pause writeback if cache full and origin being written directly dm writecache: make writeback pause configurable Rikard Falkeborn (1): dm table: Constify static struct blk_ksm_ll_ops .../admin-guide/device-mapper/writecache.rst | 25 +- block/blk-zoned.c | 119 +++- drivers/md/Makefile | 4 + drivers/md/dm-cache-target.c | 82 +-- drivers/md/dm-core.h | 65 ++ drivers/md/dm-crypt.c | 31 +- drivers/md/dm-era-target.c | 24 +- drivers/md/dm-flakey.c | 7 +- drivers/md/dm-io-tracker.h | 81 +++ drivers/md/dm-kcopyd.c | 41 +- drivers/md/dm-linear.c | 7 +- drivers/md/dm-ps-io-affinity.c | 1 - drivers/md/dm-raid1.c | 2 +- drivers/md/dm-table.c | 23 +- drivers/md/dm-thin-metadata.c | 91 +-- drivers/md/dm-writecache.c | 140 ++++- drivers/md/dm-zone.c | 660 +++++++++++++++++++++ drivers/md/dm-zoned-metadata.c | 7 + drivers/md/dm-zoned-reclaim.c | 2 +- drivers/md/dm.c | 208 ++----- drivers/md/dm.h | 30 +- drivers/md/persistent-data/dm-array.c | 52 +- drivers/md/persistent-data/dm-btree-internal.h | 13 + drivers/md/persistent-data/dm-btree-remove.c | 7 +- drivers/md/persistent-data/dm-btree-spine.c | 16 +- drivers/md/persistent-data/dm-btree.c | 542 +++++++++++++++-- drivers/md/persistent-data/dm-btree.h | 10 +- drivers/md/persistent-data/dm-space-map-common.c | 534 ++++++++++++++++- drivers/md/persistent-data/dm-space-map-common.h | 34 +- drivers/md/persistent-data/dm-space-map-disk.c | 83 +-- drivers/md/persistent-data/dm-space-map-metadata.c | 105 ++-- drivers/md/persistent-data/dm-space-map.h | 18 +- .../md/persistent-data/dm-transaction-manager.c | 61 ++ .../md/persistent-data/dm-transaction-manager.h | 22 +- include/linux/blk_types.h | 1 + include/linux/blkdev.h | 12 + include/linux/device-mapper.h | 9 +- include/linux/dm-kcopyd.h | 1 + 38 files changed, 2548 insertions(+), 622 deletions(-) create mode 100644 drivers/md/dm-io-tracker.h create mode 100644 drivers/md/dm-zone.c
