Thanks!
After waiting some seconds after device_del:
(qemu) device_del spdk_vhost_blk2
sleep 5
(qemu) chardev-remove spdk_vhost_blk2
Error: Chardev 'spdk_vhost_blk2' is busy
It works. However, I find some crashes about the vhost-user-blk.
I will send out the patches after all tests.
Thanks,

Hello Everyone,
Here are fixes for bugs that I found in my tests.

net/colo-compare.c: Create event_bh with the right AioContext
chardev/char.c: Use qemu_co_sleep_ns if in coroutine
net/colo-compare.c: Fix deadlock
chardev/char.c | 7 +++-
net/c
qemu_bh_new will set the bh to be executed in the main
loop. This causes problems as colo_compare_handle_event assumes
that it has exclusive access the queues, which are also
accessed in the iothread. It also assumes that it runs in a
different thread than the caller and takes the appropriate
locks
The chr_out chardev is connected to a filter-redirector
running in the main loop. qemu_chr_fe_write_all might block
here in compare_chr_send if the (socket-)buffer is full.
If another filter-redirector in the main loop want's to
send data to chr_pri_in it might also block if the buffer
is full. Thi
This will be needed in the next patch.

If table size is changed between virt_acpi_build and
virt_acpi_build_update, the table size would not be updated to
UEFI, therefore, just align the size to 128kb, which is enough
and same with x86. It would warn if 64k is not enough and the
align size should be updated.

It's safer to expand in_flight request to start before enter to
coroutine in synchronous wrappers and end after BDRV_POLL_WHILE loop.
Note that qemu_coroutine_enter may only schedule the coroutine in some
circumstances.

Hi all!
This is inspired by Kevin's
"block: Fix blk->in_flight during blk_wait_while_drained()" series.
So, like it's now done for block-backends, let's expand
in_flight-protected sections for bdrv_ interfaces, including
coroutine_enter and BDRV_POLL_WHILE loop into these sections.

bdrv_co_flush and bdrv_co_pdiscard will become static in further patch,
move their usage down.

bdrv_is_allocated_above creates new coroutine on each iteration if
called from non-coroutine context. To simplify expansion of in_flight
inc/dec sections in further patch let's refactor it.

The io_uring_enter(2) syscall returns with errno=EINTR when interrupted
by a signal. Retry the syscall in this case.
It's essential to do this in the io_uring_submit_and_wait() case. My
interpretation of the Linux v5.5 io_uring_enter(2) code is that it
shouldn't affect the io_uring_submit() case
