Comment # 5 on bug 1222429 from Wenruo Qu

Personally speaking, if you're going to use "rescue=" option, your fs is
already screwed up on most cases.

Furthermore, most rescue= options would require ro mount option, and can not be
remounted to RW, this is by design.

So I do not think we need "norecovery" mount option for btrfs at all.

Any more explanation on the "norecovery" mount option usage? Maybe I'm missing
something critical.
