Mike ---------------------------------------------------------------- - Biggest change this cycle is to remove support for the legacy IO path (.request_fn) from request-based DM. Jens has already started preparing for complete removal of the legacy IO path in 4.21 but this earlier removal of support from DM has been coordinated with Jens (as evidenced by the commit being attributed to him). Making request-based DM exclussively blk-mq only cleans up that portion of DM core quite nicely. - Convert the thinp and zoned targets over to using refcount_t where applicable. - A couple fixes to the DM zoned target for refcounting and other races buried in the implementation of metadata block creation and use. - Small cleanups to remove redundant unlikely() around a couple WARN_ON_ONCE(). - Simplify how dm-ioctl copies from userspace, eliminating some potential for a malicious user trying to change the executed ioctl after its processing has begun. - Tweaked DM crypt target to use the DM device name when naming the various workqueues created for a particular DM crypt device (makes the N workqueues for a DM crypt device more easily understood and enhances user's accounting capabilities at a glance via "ps") - Small fixup to remove dead branch in DM writecache's memory_entry(). ---------------------------------------------------------------- Damien Le Moal (2): dm zoned: fix metadata block ref counting dm zoned: fix various dmz_get_mblock() issues Heinz Mauelshagen (1): dm raid: avoid bitmap with raid4/5/6 journal device Igor Stoppa (1): dm: remove unnecessary unlikely() around WARN_ON_ONCE() Jens Axboe (1): dm: remove legacy request-based IO path John Pittman (2): dm thin: use refcount_t for thin_c reference counting dm zoned: target: use refcount_t for dm zoned reference counters Michał Mirosław (2): dm: add dm_table_device_name() dm crypt: make workqueue names device-specific Mike Snitzer (3): dm: rename DM_TYPE_MQ_REQUEST_BASED to DM_TYPE_REQUEST_BASED dm table: require that request-based DM be layered on blk-mq devices dm writecache: remove disabled code in memory_entry() Wenwen Wang (1): dm ioctl: harden copy_params()'s copy_from_user() from malicious users drivers/md/Kconfig | 11 -- drivers/md/dm-cache-policy-smq.c | 2 +- drivers/md/dm-core.h | 10 -- drivers/md/dm-crypt.c | 15 +- drivers/md/dm-ioctl.c | 18 +-- drivers/md/dm-mpath.c | 26 +--- drivers/md/dm-raid.c | 2 +- drivers/md/dm-rq.c | 316 ++++----------------------------------- drivers/md/dm-rq.h | 4 - drivers/md/dm-sysfs.c | 3 +- drivers/md/dm-table.c | 46 ++---- drivers/md/dm-thin.c | 8 +- drivers/md/dm-writecache.c | 5 +- drivers/md/dm-zoned-metadata.c | 80 ++++++---- drivers/md/dm-zoned-target.c | 20 +-- drivers/md/dm.c | 25 +--- drivers/md/dm.h | 1 - include/linux/device-mapper.h | 6 +- 18 files changed, 134 insertions(+), 464 deletions(-) -- dm-devel mailing list dm-devel@redhat.com https://www.redhat.com/mailman/listinfo/dm-devel
