This will allow other subsystems (i.e. fsdev) to implement throttling
without duplicating the command line options.

Hi,

Pradeep has been working on enabling throttling in 9p/fsdev. The latest
version (v11) of the patch is:

Message-Id: <1478854467-25061-1-git-send-email-pradeep.jagadeesh@huawei.com>

There is some code duplication around the command line options. This patch
is a first proposal to reduce the duplication. Some work should also be
possible on the parsing side (see fsdev_throttle_parse_opts() in the patch
above).

Thanks for your comments.

Did you check if it's possible / easy to do defining a normal array
instead of a macro and using qemu_opts_append() or something similar?

No I didn't due to lack of time but maybe Pradeep may have a look in this
direction ?

Ok, and also, it will be the occasion to add the throttling options to
the legacy -virtfs command line option as well.

Ok, also I think I have to add QMP interfaces for 9p case.

I did not understand how to fix this issue? I tried putting the do - while
loop still did not work
any idea, how to fix this?
