Replacement can replace rdev during replacement io pending.
mirror->rdev/replacement might be changed during io pending. Get rdev from
it is risky. This patch series record rdev/replacement in r10bio, and get
rdev from r10bio to fix bugs in normal write. And I want to do
this for each io type later.

I personally don't like this, do things by half. I'm good with this
approch for raid10, but can you send a new version to use this for all
io?

Agreed. Please send the fix for all types.

Thanks,
Song
