First of all, thanks to Stefan Hajnoczi for his suggestions,
I made the following changes in this patch:
1. Support 0 in BDRV_POLL_WHILE_TIMEOUT(), 0 means infinite.
2. Use uint64_t timeout_ns instead of int64 timeout to name variables.
3. Use timer_pending() to check fo

QMP may will be blocked for a long time on bdrv_drained_begin() when a
network disk is configured and the network failure is just about to occur.
In theory, any command may be blocked if it calls bdrv_drained_begin().

I'm sorry for the delay in replying.

The bdrv_drained_begin() function is a blocking function. In scenarios where
network storage
is used and network links fail, it may block for a long time.
Therefore, we add a timeout parameter to control the duration of the block.

In the disable branch of qmp_block_set_io_throttle(), we call
bdrv_drained_begin().
We know that bdrv_drained_begin() is a blocking interface used to wait for all

I/O operations to complete, i.e., to wait until bs->in_flight becomes zero.

From: Zhu Yangyang
bdrv_drained_begin() is blocked for a long time when network storage is used
and the network link has just failed.
Therefore, the timeout period is set here.
