Public bug reported:
The btrfs in 2.6.31 has some blemishes which have been addressed in
Chris Mason's git (http://git.kernel.org/?p=linux/kernel/git/mason
/btrfs-unstable.git) pending merge into 2.6.32
Namely:
* ENOSPC panics
* Incorrect metadata reservation leads to disk full at somewhere around 70% of
expected disk capacity
* Huge performance increases due to smarter caching (for bootup, around a
doubled speed)
* Misc panics and oops
The regression potential is minor: These are primarily bugfix releases backward
and forward compatible for existing btrfs users, and btrfs doesn't touch
anything in the kernel tree outside of itself, so there's no chance of
regressions for non-btrfs users.
In userspace, it'd be a good idea too to update btrfs-tools to Chris's git
branch too, which adds the delete snapshot support in userland, but that's a
much more minor concern compared to the kernel aspect of this.
