Hi Linus, The DM tree is based on the block tree for this cycle because a fair amount of my time was spent working on the percpu inflight IO counters changes and other block fixes (which impact DM) that are in Jens' block pull. The following changes since commit cd19181bf9ad4b7f40f2a4e0355d052109c76529: blk-mq: enable IO poll if .nr_queues of type poll > 0 (2018-12-17 21:35:07 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git tags/for-4.21/dm-changes for you to fetch changes up to c6d6e9b0f6b4201c77f2cea3964dd122697e3543: dm: do not allow readahead to limit IO size (2018-12-18 14:23:41 -0500) Please pull, thanks. Mike ---------------------------------------------------------------- - Eliminate a couple indirect calls from bio-based DM core. - Fix DM to allow reads that exceed readahead limits by setting io_pages in the backing_dev_info. - A couple code cleanups in request-based DM. - Fix various DM targets to check for device sector overflow if CONFIG_LBDAF is not set. - Use u64 instead of sector_t to store iv_offset in DM crypt; sector_t isn't large enough on 32bit when CONFIG_LBDAF is not set. - Performance fixes to DM's kcopyd and the snapshot target focused on limiting memory use and workqueue stalls. - Fix typos in the integrity and writecache targets. - Log which algorithm is used for dm-crypt's encryption and dm-integrity's hashing. - Fix false -EBUSY errors in DM raid target's handling of check/repair messages. - Fix DM flakey target's corrupt_bio_byte feature to reliably corrupt the Nth byte in a bio's payload. ---------------------------------------------------------------- AliOS system security (1): dm crypt: use u64 instead of sector_t to store iv_offset Colin Ian King (1): dm integrity: fix spelling mistake in workqueue name Eric Biggers (2): dm crypt: log the encryption algorithm implementation dm verity: log the hash algorithm implementation Heinz Mauelshagen (1): dm raid: fix false -EBUSY when handling check/repair message Jaegeuk Kim (1): dm: do not allow readahead to limit IO size Mike Snitzer (3): dm rq: remove unused arguments from rq_completed() dm: remove indirect calls from __send_changing_extent_only() dm rq: cleanup leftover code from recently removed q->mq_ops branching Mikulas Patocka (1): dm: avoid indirect call in __dm_make_request Milan Broz (1): dm: Check for device sector overflow if CONFIG_LBDAF is not set Nikos Tsironis (2): dm snapshot: Fix excessive memory usage and workqueue stalls dm kcopyd: Fix bug causing workqueue stalls Shenghui Wang (2): dm writecache: fix typo in error msg for creating writecache_flush_thread dm bufio: update comment in dm-bufio.c Sweet Tea (1): dm flakey: Properly corrupt multi-page bios. wuzhouhui (1): dm mpath: only flush workqueue when needed drivers/md/dm-bufio.c | 12 +++++------ drivers/md/dm-crypt.c | 17 ++++++++++++---- drivers/md/dm-delay.c | 2 +- drivers/md/dm-flakey.c | 35 +++++++++++++++++++++----------- drivers/md/dm-integrity.c | 2 +- drivers/md/dm-kcopyd.c | 19 +++++++++++++----- drivers/md/dm-linear.c | 2 +- drivers/md/dm-mpath.c | 6 ++++-- drivers/md/dm-raid.c | 3 +-- drivers/md/dm-raid1.c | 3 ++- drivers/md/dm-rq.c | 18 ++++++----------- drivers/md/dm-snap.c | 22 +++++++++++++++++++++ drivers/md/dm-table.c | 3 +++ drivers/md/dm-unstripe.c | 2 +- drivers/md/dm-verity-target.c | 9 +++++++++ drivers/md/dm-writecache.c | 2 +- drivers/md/dm.c | 46 ++++++++++++------------------------------- 17 files changed, 121 insertions(+), 82 deletions(-)
