Linus Torvalds 83c7c18b16 - DM core passthrough ioctl fix to retain reference to DM table, and
that table's block devices, while issuing the ioctl to one of those
   block devices.
 
 - DM core passthrough ioctl fix to _not_ override the fmode_t used to
   issue the ioctl.  Overriding by using the fmode_t that the block
   device was originally open with during DM table load is a liability.
 
 - Add DM core support for secure erase forwarding and update the DM
   linear and DM striped targets to support them.
 
 - A DM core 4.16 stable fix to allow abnormal IO (e.g. discard, write
   same, write zeroes) for targets that make use of the non-splitting IO
   variant (as is done for multipath or thinp when layered directly on
   NVMe).
 
 - Allow DM targets to return a payload in response to a DM message that
   they are sent.  This is useful for DM targets that would like to
   provide statistics data in response to DM messages.
 
 - Update DM bufio to support non-power-of-2 block sizes.  Numerous other
   related changes prepare the DM bufio code for this support.
 
 - Fix DM crypt to use a bounded amount of memory across the entire
   system.  This is to avoid OOM that can otherwise occur in response to
   certain pathological IO workloads (e.g. discarding a large DM crypt
   device).
 
 - Add a 'check_at_most_once' feature to the DM verity target to allow
   verity to be used on mobile devices that have very limited resources.
 
 - Fix the DM integrity target to fail early if a keyed algorithm
   (e.g. HMAC) is to be used but the key isn't set.
 
 - Add non-power-of-2 support to the DM unstripe target.
 
 - Eliminate the use of a Variable Length Array in the DM stripe target.
 
 - Update the DM log-writes target to record metadata (REQ_META flag).
 
 - DM raid fixes for its nosync status and some variable range issues.
