[Qemu-devel] [PATCH v5] hmp: add info iothreads command

[Qemu-devel] [PATCH v5] hmp: add info iothreads command

[Ting Wang]

Make "info iothreads" available on the HMP monitor.

For example, the results are as follows when executing qemu
command with "-object iothread,id=iothread-1 -object 
iothread,id=iothread-2".
(qemu) info iothreads
iothread-1: thread_id=123
iothread-2: thread_id=456

How about add a '\' at the beginning of each line? similar as the
output of 'info network'

For 'info network', the \ represents the peer relationship between e.g.
NIC and backend.  There is no such relationship for iothreads.

Applied to my qapi-next[*] branch, thanks!

[*] Close enough --- can't be bothered to create a separate monitor-next
branch right now :)
