Pull device mapper updates from Mike Snitzer: - Add encrypted byte-offset initialization vector (eboiv) to DM crypt. - Add optional discard features to DM snapshot which allow freeing space from a DM device whose free space was exhausted. - Various small improvements to use struct_size() and kzalloc(). - Fix to check if DM thin metadata is in fail_io mode before attempting to update the superblock to set the needs_check flag. Otherwise the DM thin-pool can hang. - Fix DM bufio shrinker's potential for ABBA recursion deadlock with DM thin provisioning on loop usecase. * tag 'for-5.3/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm bufio: fix deadlock with loop device dm snapshot: add optional discard support features dm crypt: implement eboiv - encrypted byte-offset initialization vector dm crypt: remove obsolete comment about plumb IV dm crypt: wipe private IV struct after key invalid flag is set dm integrity: use kzalloc() instead of kmalloc() + memset() dm: update stale comment in end_clone_bio() dm log writes: fix incorrect comment about the logged sequence example dm log writes: use struct_size() to calculate size of pending_block dm crypt: use struct_size() when allocating encryption context dm integrity: always set version on superblock update dm thin metadata: check if in fail_io mode when setting needs_check
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.
