[Btrfs-devel] experimental changes pushed out

[Chris Mason]

Hello everyone,

I've just pushed out some really experimental stuff, mostly so that
Josef is working against my latest code.

The new changes replace the extent tree preallocation code with
something less complex, and try to make tree defrag and snapshot
deletion more friendly in terms of dropping locks more frequently.

Josef, this should increase the concurrency a little for your work.
