       reshape progresses
     - raid5 fixes for lockless max_nr_stripes and recovery_offset

   allowing REQ_NOWAIT and tightening conventional zone rejection

   the blk-integrity.h include from bdev.c

 - ublk improvements: add UBLK_F_IO_DESC_SIZE, split request validation
   from io_desc init, reject non-power-of-2 zone sizes in SET_PARAMS,

Currently, io_buffer_register_bvec() takes in a request. In preparation
for supporting kernel-populated buffers in fuse io-uring (which will
need to register bvecs directly, not through a struct request), rename
this to io_buffer_register_request().

A subsequent patch will commandeer the "io_buffer_register_bvec()"
function name to support registering bvecs directly.

Rename io_buffer_unregister_bvec() to a more generic name,
io_buffer_unregister(), as both io_buffer_register_request() and
io_buffer_register_bvec() callers will use it for unregistration.

struct bvec_iter::bi_bvec_done is used an offset in the current bvec,
let's rename it accordingly for better clarity. I also plan to use it
for non-bvec based iteration in the future like dma-buf, so drop the
"bvec" part.

The "Objective" section of inline-encryption.rst suggests that
blk-crypto-fallback is just for testing.  That's no longer accurate, so
update it accordingly.  Also fix a typo later in the document.
