Hello,
Twice for past two days I caught an error with btrfs, you can see a
fragment of dmesg on http://paste.org.ru/?kz4x31 and
http://paste.org.ru/?lwdeu3
It's a buildserver with jenkins that several times an hour starts
commit d53ba47484ed6245e640ee4bfe9d21e9bfc15765
(Btrfs: use commit root when loading free space cache) has remove
the deadlock check, and the related comments can be removed as well.

The API in tree log code has done sort of changes, and it proves that
we can benifit from using token, so do the same thing here.
function_graph tracer's timer shows that it costs nearly half time
of before(39.788us - 22.391us).

This'd avoid us empty looping.
Say we have only one disk and the metadata raid type will be defaultly DUP,
and we do not need to start from index=0(RAID10) and get over two empty
loops to index=2(DUP).

Hi
I've made some updates on the wiki and I'd like a technical review for
correctness. This particular topic is already confusing - some
unnecessary sarcasm made it even more so:

That would only seem to work with btrfs on LVM which I'd think is uncommon
