Hello,
Here is a little background of my setup. mdadm->lvm->dmcrypt->btrfs.
I had the btrfs in ext4 but I converted it.
When I first did the convert, everything was fine. After a moment, I did a
btrfs balance and since that day,
the writing speed is very slow. When I do things like unzip/unra

This is getting full, 84%, there is not much chance of getting rid of
substantially many 1G-chunks through the 'usage=1' balance filter.

I think this is not a problem within btrfs at the place where this has
changed.

Someone who is root or capable(CAP_SYS_ADMIN) could corrupt the
superblock and make Btrfs printk("%s") crash while holding the
uuid_mutex since nobody forces a limit on the string. Since the
uuid_mutex is significant, the system would be unusable
afterwards.

When creating a snapshot, failing to commit a transaction can end up
with aborting the transaction, following by doing a cleanup for it, where
we'll free all snapshots pending to disk.
So we check it and avoid double free on pending snapshots.

When committing a transaction, we may bail out of running delayed refs
due to ENOSPC, and then abort the current transaction to flip into readonly.
But we'll hit a deadlock on ref head's lock since we forget to release
its lock and other cleanup stuff.

Hello list,
is btrfs ready for production use in 3.6.6? Or should i backport fixes
from 3.7-rc?
Is it planned to have a stable kernel which will get all btrfs fixes
backported?

Here is what I see in my kern.log (see below).
For me this first happened when the filesystem was close to full (less
than 1GB left), but someone on the irc channel mentioned a similar
problem on suspend to ram.
The files that have checksum failures end up with their first 4k filled
with 0x01 byt
