[PATCHv6 00/11] direct-io dma alignment

[Keith Busch <kbusch@fb.com>]

From: Keith Busch <kbusch@kernel.org>

The previous version is available here:

  https://lore.kernel.org/linux-block/Yp4qQRI5awiycml1@kbusch-mbp.dhcp.thefacebook.com/T/#m0a93b6392038aad6144e066fb5ada2cbf316f78e 

Changes from the previous are all trivial changes:

  Fixed a typo, s/bvev_/bdev_/

  Updated commit messages and reviews

  Updated code comments

  Added a new comment for request_queue dma_alignement expressly
  documenting the consequences of setting this. All existing users of
  this attribute were checked to ensure they are on the correct side of
  those consequences.

Keith Busch (11):
  block: fix infinite loop for invalid zone append
  block/bio: remove duplicate append pages code
  block: export dma_alignment attribute
  block: introduce bdev_dma_alignment helper
  block: add a helper function for dio alignment
  block/merge: count bytes instead of sectors
  block/bounce: count bytes instead of sectors
  iov: introduce iov_iter_aligned
  block: introduce bdev_iter_is_aligned helper
  block: relax direct io memory alignment
  iomap: add support for dma aligned direct-io
