Subject: [PATCHv2 0/7] direct-io: even more flexible io vectors

From: Keith Busch <kbusch@...nel.org>

This series removes the direct io requirement that io vector lengths
align to the logical block size.

Changes from v1:

 - Fixed the return value when attempting to align a built bio to a
   block size multiple.

 - Added reviews

Keith Busch (7):
  block: check for valid bio while splitting
  block: align the bio after building it
  block: simplify direct io validity check
  iomap: simplify direct io validity check
  block: remove bdev_iter_is_aligned
  blk-integrity: use simpler alignment check
  iov_iter: remove iov_iter_is_aligned
