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.
V7:
- add protection for aborting in laio_attach_aio_context(), as suggested
by Stefan, 1/3
- patch style, return real aborting failure to caller, as suggested
by Kevin, 1/3
- track pending I/O and only handle -EAGAIN if there is pending I/O,
pointed by Kevin, 2/3
V6:
- don't pass ioq_submit() return value to ioq_enqueue(), as suggested
by Stefan
- fix one build failure introduced in V5, reported 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

- rebase on QEMU master
V2:
