[PATCH v3 0/1] Patch to adjust coroutine pool size adaptively

[Hiroki Narukawa]

Resending patch with decreasing coroutine pool size on device remove

We encountered random disk IO performance drop since qemu-5.0.0, and this patch 
fixes it.

Commit message in c740ad92 implied to adjust coroutine pool size adaptively, so 
I tried to implement this.

Changes from v2:
Decrease coroutine pool size on device remove

Changes from v1:
Use qatomic_read properly
