Linus Torvalds 0e306952d7 - Fix DM thinp discard performance regression introduced during 6.4
merge; where DM core was splitting large discards every 128K
   (max_sectors_kb) rather than every 64M (discard_max_bytes).
 
 - Extend DM core LOCKFS fix, made during 6.4 merge, to also fix race
   between do_mount and dm's do_suspend (in addition to the earlier
   fix's do_mount race with dm's do_resume).
 
 - Fix DM thin metadata operations to first check if the thin-pool is
   in "fail_io" mode; otherwise UAF can occur.
 
 - Fix DM thinp's call to __blkdev_issue_discard to use GFP_NOIO rather
   than GFP_NOWAIT (__blkdev_issue_discard cannot handle NULL return
   from bio_alloc).

Pull device mapper fixes from Mike Snitzer:

 - Fix DM thinp discard performance regression introduced during this
   merge window where DM core was splitting large discards every 128K
   (max_sectors_kb) rather than every 64M (discard_max_bytes).

 - Extend DM core LOCKFS fix, made during 6.4 merge, to also fix race
   between do_mount and dm's do_suspend (in addition to the earlier
   fix's do_mount race with dm's do_resume).

 - Fix DM thin metadata operations to first check if the thin-pool is in
   "fail_io" mode; otherwise UAF can occur.

 - Fix DM thinp's call to __blkdev_issue_discard to use GFP_NOIO rather
   than GFP_NOWAIT (__blkdev_issue_discard cannot handle NULL return
   from bio_alloc).

README

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.
