Hi Shaohua,
you asked me to resend this (second) patch with improved
comments back in November, and it completely slipped my mind - sorry.
I decided the comments would fit better in a separate patch,
so following are a patch to add comments, and then the bugfix
patch marked for -stable.
You asked:
This will bypass hotadd too, is it what we want?
No, it doesn't. In the only cases where the patch makes a
difference, a non-NULL rdev will have been passed as "this",
so hot-add will be skipped anyway.
This patch includes a bugfix as reported by yuyufen
Thanks,
NeilBrown
