Linus Torvalds 6cdc577a18 - Update bio-based DM core to always call blk_queue_split() and update
DM targets to properly advertise discard limits that blk_queue_split()
   looks at when dtermining to split discard.  Whereby allowing DM core's
   own 'split_discard_bios' to be removed.
 
 - Improve DM cache target to provide support for discard passdown to the
   origin device.
 
 - Introduce support to directly boot to a DM mapped device from init by
   using dm-mod.create= module param.  This eliminates the need for an
   elaborate initramfs that is otherwise needed to create DM devices.
   This feature's implementation has been worked on for quite some time
   (got up to v12) and is of particular interest to Android and other
   more embedded platforms (e.g. ARM).
 
 - Rate limit errors from the DM integrity target that were identified as
   the cause for recent NMI hangs due to console limitations.
 
 - Add sanity checks for user input to thin-pool and external snapshot
   creation.
 
 - Remove some unused leftover kmem caches from when old .request_fn
   request-based support was removed.
 
 - Various small cleanups and fixes to targets (e.g. typos, needless
   unlikely() annotations, use struct_size(), remove needless
   .direct_access method from dm-snapshot)
