[Qemu-devel] [PATCH v5 0/3] linux-aio: fix batch submission

[Ming Lei <ming.lei@canonical.com>]

The 1st patch fixes batch submission.

The 2nd one fixes -EAGAIN for non-batch case.

The 3rd one is a cleanup.

This patchset is splitted from previous patchset(dataplane: optimization
and multi virtqueue support), as suggested by Stefan.

V5:
    - in case of submission failure, return -EIO for new coming requests
      until aborting is handled
	- in patch2, follow Paolo's suggestion about ioq_enqueue() changes

V4:
	- abort reuqests in BH to abvoid potential "Co-routine re-entered recursively"
	- remove 'enqueue' parameter to ioq_submit() to simpify change
	- beautify code as suggested by Paolo

v3:
    - rebase on QEMU master
v2:
    - code style fix and commit log fix as suggested by Benoît Canet
v1:
    - rebase on latest QEMU master
