Dear Zhang,


Thank you for your patch. Some nits.

Please add a space before the (. “Fix it.” also fits on the line above,
and maybe use plural in the commit message summary. For the body, maybe:

Fix spelling of dones't and waitting in comments.

Version your patches, you're now at v2. [PATCH v2] ...

Please find a few suggestions below as to what can be fixed in this
block of text as you're making a pass over it.

There are several mentions of 'reconfig mutex' that should probably be
'reconfig_mutex'. What's the correct way to refer to a mutex in comments
like the above?

Sorry for getting on this late.

AFAICT, this one doesn't apply any more (conflict with some of your
other fixes). Could you please resend?

Thanks,
