[PATCH v3 0/3] btrfs: quasi-round-robin for chunk allocation
In a multi device setup, the chunk allocator currently always allocates
chunks on the devices in the same order. This leads to a very uneven
distribution, especially with RAID1 or RAID10 and an uneven number of
devices.
This patch always sorts the devices before allocating, and allocates the
stripes on the devices with the most available space, as long as there
is enough space available. In a low

[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.
