[Qemu-devel] [PATCH resend 0/7] Discard improvements

[Paolo Bonzini]

This series builds on the patch from Kusanagi Kouichi, and also adds
discard support for non-passthrough block devices (BLKDISCARD), and
asynchronous discard support.

SCSI already calls bdrv_aio_discard, so it is not affected by these
patches.

Kusanagi Kouichi (1):
  raw-posix: support discard on more filesystems

Paolo Bonzini (6):
  raw-posix: remember whether discard failed
  raw: support discard on block devices
  block: make discard asynchronous
  ide: fix TRIM with empty range entry
  ide: issue discard asynchronously but serialize the pieces
  block: clear dirty bitmap when discarding
