bio-based code so that it follows patterns established by request-based code. - Request-based DM core improvement to eliminate unnecessary call to blk_mq_queue_stopped(). - Add "panic_on_corruption" error handling mode to DM verity target. - DM bufio fix to to perform buffer cleanup from a workqueue rather than wait for IO in reclaim context from shrinker. - DM crypt improvement to optionally avoid async processing via workqueues for reads and/or writes -- via "no_read_workqueue" and "no_write_workqueue" features. This more direct IO processing improves latency and throughput with faster storage. Avoiding workqueue IO submission for writes (DM_CRYPT_NO_WRITE_WORKQUEUE) is a requirement for adding zoned block device support to DM crypt. - Add zoned block device support to DM crypt. Makes use of DM_CRYPT_NO_WRITE_WORKQUEUE and a new optional feature (DM_CRYPT_WRITE_INLINE) that allows write completion to wait for encryption to complete. This allows write ordering to be preserved, which is needed for zoned block devices. - Fix DM ebs target's check for REQ_OP_FLUSH. - Fix DM core's report zones support to not report more zones than were requested. - A few small compiler warning fixes. - DM dust improvements to return output directly to the user rather than require they scrape the system log for output. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAl8tdOQTHHNuaXR6ZXJA cmVkaGF0LmNvbQAKCRDFI/EKLZ0DWvDlB/sF8svagDqeqs27xTxCiUPykD29cMmS OGPr0Mp/BntZOBpSaTPM9s5XucP3WJhPsxet5qeoyM3OViSFx+O55PqPjn8C65y0 eGMa4zknd9eO1933+ijmyQu6VNr4sf/6nusX4xSGqv00UR22dJ+3pHtfN9ANDXYX AAYA0Ve6UuOwAbGUCnRGI/2780aYY0B8Ok+cF21CskqryF+RpmbZ6BsR07+Hk4cy LX5EaHUqezW12cibLq2f0l7TLLJ86OscvqyU9lGVIxiV57e2i5c2S1HvhKZu+Wn3 6CUmlOhGI0viCKgM1ArekZ+zOw9ROIaAKKPzC5mspqx9yuuCqdY8k8xV =X3tt -----END PGP SIGNATURE----- Merge tag 'for-5.9/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - DM multipath locking fixes around m->flags tests and improvements to bio-based code so that it follows patterns established by request-based code. - Request-based DM core improvement to eliminate unnecessary call to blk_mq_queue_stopped(). - Add "panic_on_corruption" error handling mode to DM verity target. - DM bufio fix to to perform buffer cleanup from a workqueue rather than wait for IO in reclaim context from shrinker. - DM crypt improvement to optionally avoid async processing via workqueues for reads and/or writes -- via "no_read_workqueue" and "no_write_workqueue" features.
