- 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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJcHu6MAAoJEMUj8QotnQNar9gIAKyJ5hH0ik3mlLhAyPcMkRU+ MPvjTAC8V5V33VY8YqKD/TcDHY8yaGTPKSK0SAnB8Jv2tLz8mp0H18syJbMvNcFc MS/xWYLAZiXf5xJ4eJpo8ayDvU6DAkKtSbG7VHJ8gnx/WV8bW1b90OCIq8GN+jHo DPp6RDzy3LvonoZ9OPognQKUDXK1crdPDiv1Wzw9Zjd4JlruIaGgJOc1RLB7YdVK u5c7UD7cT+MCROEzJrctAZa5oRVhuemd83HPvwE2akRFvCSNtc7aIVtNfJ79nqL7 19oUDfsuzf2zkiJLzO0oU4OrJ+lUGDJf/sPXmU1qlPyKdUqYKFxT+KHvBnhAQXI= =pCs8 -----END PGP SIGNATURE----- Merge tag 'for-4.21/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - 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. * tag 'for-4.21/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: do not allow readahead to limit IO size dm raid: fix false -EBUSY when handling check/repair message dm rq: cleanup leftover code from recently removed q->mq_ops branching dm verity: log the hash algorithm implementation dm crypt: log the encryption algorithm implementation dm integrity: fix spelling mistake in workqueue name dm flakey: Properly corrupt multi-page bios. dm: Check for device sector overflow if CONFIG_LBDAF is not set dm crypt: use u64 instead of sector_t to store iv_offset dm kcopyd: Fix bug causing workqueue stalls dm snapshot: Fix excessive memory usage and workqueue stalls dm bufio: update comment in dm-bufio.c dm writecache: fix typo in error msg for creating writecache_flush_thread dm: remove indirect calls from __send_changing_extent_only() dm mpath: only flush workqueue when needed dm rq: remove unused arguments from rq_completed() dm: avoid indirect call in __dm_make_request |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
