So this crash means we failed to write all the blocks required to commit the transaction. The reason is that we're getting failed bios to the missing device, and that failure isn't properly eaten by the raid aware endio code. If you pull the top commit from my for-linus branch, it should all work. I know you've got a big FS here, I haven't tested this on raid10 yet, only raid1. If you want to wait a bit for safety I'll do a raid10 run too. The fix looks good to me, and I've tested it on raid10. Thanks Chris and Li. I can confirm that this fixed my issues on raid10 as well.

Re: BUG during btrfs device delete missing
Hi Chris, This was on 3.2-rc2 but I tried with rc4 and it segfaulted again. I think the traces were the same but I've rebooted and can't say for sure.
