While the pblk argument to fscrypt_zeroout_range is declared as a
sector_t, it actually is interpreted as a logical block size unit, which
is highly unusual. Switch to passing the 512 byte units that sector_t is
defined for.

blk-crypto: handle the fallback above the block layer2026-01-11T19:55:41+00:00Christoph Hellwighch@lst.de2026-01-09T06:07:49+00:00urn:sha1:bb8e2019ad613dd023a59bf91d1768018d17e09b
Add a blk_crypto_submit_bio helper that either submits the bio when
it is not encrypted or inline encryption is provided, but otherwise
handles the encryption before going down into the low-level driver.
This reduces the risk from bio reordering and keeps memory allocation
as high up in the stack as possible.
Note that if the submitter knows that inline enctryption is known to
be supported by the underyling driver, it can still use plain
submit_bio.

fscrypt: keep multiple bios in flight in fscrypt_zeroout_range_inline_crypt2026-01-11T19:55:41+00:00Christoph Hellwighch@lst.de2026-01-09T06:07:42+00:00urn:sha1:bc26e2efa2c5bb9289fa894834446840dea0bc31
This should slightly improve performance for large zeroing operations,
but more importantly prepares for blk-crypto refactoring that requires
all fscrypt users to call submit_bio directly.
