Linus Torvalds b3298500b2 - Fix DM's bio splitting changes that were made during v5.9.
Restores splitting in terms of varied per-target ti->max_io_len
   rather than use block core's single stacked 'chunk_sectors' limit.
 
 - Like DM crypt, update DM integrity to not use crypto drivers that
   have CRYPTO_ALG_ALLOCATES_MEMORY set.
 
 - Fix DM writecache target's argument parsing and status display.
 
 - Remove needless BUG() from dm writecache's persistent_memory_claim()
 
 - Remove old gcc workaround in DM cache target's block_div() for ARM
   link errors now that gcc >= 4.9 is required.
 
 - Fix RCU locking in dm_blk_report_zones and dm_dax_zero_page_range.
 
 - Remove old, and now frowned upon, BUG_ON(in_interrupt()) in
   dm_table_event().
 
 - Remove invalid sparse annotations from dm_prepare_ioctl() and
   dm_unprepare_ioctl().

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.
