Re: [PATCH v2] md/cluster: block reshape requests with resync job initiated from remote node

["heming.zhao@suse.com" <heming.zhao@suse.com>]

Hello Song & Guoqing,

Thank you for your kindly review.
I feel it's unclear and mess up to put patch 1 & 2 together.
So I split them and first send patch 1 for review.

I am not sure whether I should add "reviewd-by Song & Guoqing" in comments.
Because the code is correct, comments need to revise.

btw,
For patch 2, I need some time to answer Guoqing's question. please wait.

Thanks.
