[PATCH 1/5] fs: allow short direct-io reads to be completed via buffered IO V2
V1->V2: Check to see if our current ppos is >= i_size after a short DIO read,
just in case it was actually a short read and we need to just return.
This is similar to what already happens in the write case. If we have a short
read while doing O_DIRECT, instead of just returning, fallthrough and try to
read the rest via buffered IO. BTRFS needs this because if we encounter a

[PATCH] Btrfs: fix a deadlock on chunk mutex
An user reported that he has hit an annoying deadlock while playing with
ceph based on btrfs.
Current updating device tree requires space from METADATA chunk,
so we -may- need to do a recursive chunk allocation when adding/updating
dev extent, that is where the deadlock comes from.
If we use SYSTEM metadata to update device tree, we can avoid the recursive
stuff.
