[Qemu-devel] [PATCH 0/5] Byte-based block limits

[Eric Blake <eblake@redhat.com>]

BlockLimits is currently an ugly mix of byte limits vs.
sector limits.  Unify it.  Fix some bugs I found in
bdrv_aligned_preadv() while at it.

Probably conflicts with Kevin's ongoing work to migrate
bdrv_aligned_preadv() to be byte-based, but I found this
handy before tackling conversion of 'discard' interfaces,
and before implementing an auto-fragmenting to max_transfer
size at the block layer.

Also available as a tag at:
git fetch git://repo.or.cz/qemu/ericb.git nbd-limits-v1

Eric Blake (5):
  block: Tighter assertions on bdrv_aligned_preadv()
  block: Honor flags during bdrv_aligned_preadv()
  block: Switch transfer length bounds to byte-based
  block: Switch discard length bounds to byte-based
  block: Move request_alignment into BlockLimit
