[PULL 1/3] virtio-blk: deprecate SCSI passthrough

[Stefan Hajnoczi]

The Linux virtio_blk.ko guest driver is removing legacy SCSI passthrough
support.  Deprecate this feature in QEMU too.

[PULL 2/3] docs: fix rst syntax errors in unbuilt docs

[Stefan Hajnoczi]

The .rst files outside docs/{devel,interop,specs} aren't built yet and
therefore a few syntax errors have slipped through.  Fix them.

[PULL 3/3] virtio-blk: fix out-of-bounds access to bitmap in notify_guest_bh

From: Li Hangjing <lihangjing@baidu.com>

When the number of a virtio-blk device's virtqueues is larger than
BITS_PER_LONG, the out-of-bounds access to bitmap[ ] will occur.

Re: [PULL 0/3] Block patches

[Stefan Hajnoczi]

It looks like a race condition in the test case. The failed test case
(tests/unit/test-aio.c:test_timer_schedule()) assumes the process will
be scheduled in a timely manner. A timer is scheduled for 750 ms and
the test waits for 1 second before running the event loop. At that
point a callback schedules the timer another 750 ms in the future. The
problem is that the exact sequence of event loop (aio_poll())
invocations can be unexpected on a heavily loaded CI runner leading to
spurious test failures.

I re-ran the job and it passed:
https://gitlab.com/qemu-project/qemu/-/jobs/2430529496

I also ran it locally under Wine and didn't see a failure.

FWIW I'm about to send another block pull request and it will include
these patches again. Feel free to wait for the next pull request.
