- A stable fix for the DM cache target that fixes the potential for data corruption after an unclean shutdown of a cache device using writeback mode. - Update DM integrity target to allow the metadata to be stored on a separate device from data. - Fix DM kcopyd and the snapshot target to cond_resched() where appropriate and be more efficient with processing completed work. - A few fixes and improvements for DM crypt. - Add DM delay target feature to configure delay of flushes independent of writes. - Update DM thin-provisioning target to include metadata_low_watermark threshold in pool status. - Fix stale DM thin-provisioning Documentation. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJbddbuAAoJEMUj8QotnQNaoZIH/1qxc4x26bUfkVwBCiqU0cqJ 8PD8D5UBFB7+JXeI4P9p7ONVJNpk291QGeX+CBOXfhdeBBcXmuHnavJFcmH6+1Y3 omPEIvKnsODEMyZuznA8HasvlZIDPNOESaDt/8vhDPkDmPLWi3h+fUO1ay+NRtua J+8ZTe35P5SY70uLFE3nTeZScZD8KAO9Py1W+5Lz1godS6UUHhNOAcm0zzw5Nvnc 2gu2HZaCx0erFNou5Kj5Y4a/z/cITlAyXHQyzXBINk/X4sSwvzRr2tSy/FG91CuO kHduB0Tgo8eSeEta8jcOcYCm601XLlXzkIM69Z7c3fmCY+b8dY4ybHPxApTEv7c= =blC6 -----END PGP SIGNATURE----- Merge tag 'for-4.19/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - A couple stable fixes for the DM writecache target. - A stable fix for the DM cache target that fixes the potential for data corruption after an unclean shutdown of a cache device using writeback mode. - Update DM integrity target to allow the metadata to be stored on a separate device from data. - Fix DM kcopyd and the snapshot target to cond_resched() where appropriate and be more efficient with processing completed work. - A few fixes and improvements for DM crypt. - Add DM delay target feature to configure delay of flushes independent of writes. - Update DM thin-provisioning target to include metadata_low_watermark threshold in pool status. - Fix stale DM thin-provisioning Documentation. * tag 'for-4.19/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (26 commits) dm writecache: fix a crash due to reading past end of dirty_bitmap dm crypt: don't decrease device limits dm cache metadata: set dirty on all cache blocks after a crash dm snapshot: remove stale FIXME in snapshot_map() dm snapshot: improve performance by switching out_of_order_list to rbtree dm kcopyd: avoid softlockup in run_complete_job dm cache metadata: save in-core policy_hint_size to on-disk superblock dm thin: stop no_space_timeout worker when switching to write-mode dm kcopyd: return void from dm_kcopyd_copy() dm thin: include metadata_low_watermark threshold in pool status dm writecache: report start_sector in status line dm crypt: convert essiv from ahash to shash dm crypt: use wake_up_process() instead of a wait queue dm integrity: recalculate checksums on creation dm integrity: flush journal on suspend when using separate metadata device dm integrity: use version 2 for separate metadata dm integrity: allow separate metadata device dm integrity: add ic->start in get_data_sector() dm integrity: report provided data sectors in the status dm integrity: implement fair range locks ... |

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
