- Fix DM thinp's discard passdown to properly account for extra reference that is taken to guard against reallocating a block before a discard has been issued. - Fix bio-based DM's redundant IO accounting that was occurring for bios that must be split due to the nature of the DM target (e.g. dm-stripe, dm-thinp, etc). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJcShLOAAoJEMUj8QotnQNahKwIAKtIHVmexvytppeapY0JkW+r eAVvfAmy/wnAir1P4jAM5/vIFydwdiOy9XmJxoB5yZHr7iG7Yhf+N58sN0Bk8SIH whUmt7MI8bMYkXhJNrEhiWbDDnEc55C7xdAqAYGDH7j2lJEkdnR6hdL5fDnMnCyx AxbQhAIXOWUCaDZKHQ8VQquq0EDg/LElCaGPWMJ71YTjgoNWV4MvQWqLqk/KJEyb JfYR+5yaAVlqoysIb+gQtn4+UNA5oU8jSYe1rqrdfZ1fYx5ZYhlhp4gHM3+tD4gL 4zEOPD0iP1hrGc+4ZgWmFT2fZVHcUHcUb8+UnkH52t5QFhnghnTQSnRsaWviqAg= =ew3d -----END PGP SIGNATURE----- Merge tag 'for-5.0/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix DM crypt's parsing of extended IV arguments. - Fix DM thinp's discard passdown to properly account for extra reference that is taken to guard against reallocating a block before a discard has been issued. - Fix bio-based DM's redundant IO accounting that was occurring for bios that must be split due to the nature of the DM target (e.g. dm-stripe, dm-thinp, etc). * tag 'for-5.0/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: add missing trace_block_split() to __split_and_process_bio() dm: fix dm_wq_work() to only use __split_and_process_bio() if appropriate dm: fix redundant IO accounting for bios that need splitting dm: fix clone_bio() to trigger blk_recount_segments() dm thin: fix passdown_double_checking_shared_status() dm crypt: fix parsing of extended IV arguments
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.
