In addition to resize support, add # optional discard support with the "allow_discards" feature. # # - Fix DM clone target's discard handling and overflow bugs which could # cause data corruption. # # - Fix memory leak in destructor for DM verity FEC support. # # - Fix DM zoned target's redundant increment of nr_rnd_zones. # # - Small cleanup in DM crypt to use crypt_integrity_aead() helper. # # * tag 'for-5.7/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: # dm clone metadata: Fix return type of dm_clone_nr_of_hydrated_regions() # dm clone: Add missing casts to prevent overflows and data corruption # dm clone: Add overflow check for number of regions # dm clone: Fix handling of partial region discards # dm writecache: add cond_resched to avoid CPU hangs # dm integrity: improve discard in journal mode # dm integrity: add optional discard support # dm integrity: allow resize of the integrity device # dm integrity: factor out get_provided_data_sectors() # dm integrity: don't replay journal data past the end of the device # dm integrity: remove sector type casts # dm integrity: fix a crash with unusually large tag size # dm zoned: remove duplicate nr_rnd_zones increase in dmz_init_zone() # dm verity fec: fix memory leak in verity_fec_dtr # dm writecache: optimize superblock write # dm writecache: implement gradual cleanup # dm writecache: implement the "cleaner" policy # dm writecache: do direct write if the cache is full # dm integrity: print device name in integrity_metadata() error message # dm crypt: use
