Hi everyone,
I try to keep most of the btrfs commits against the last release. This
way, people can update their old and crusty kernels from 3 months ago,
and still have the latest btrfs code.
We do have one commit that is 3.2 specific though, so I put it into a
for-linus-3.2 branch:
git://git.

a few weeks of tracing our delalloc reservations from Josef, and then
fixing up the related bugs.
Outside of Josef's patches we have some assorted fi
Hi!
On apt-get dist-upgrading my Amarok ThinkPad T23 with BTRFS as /
and as /home I get extremely slow operation - my ThinkPad T42 with Ext4
is running circles around it and thats likely not only due to the faster CPU.
vmstat 1 shows:

I recommend to run defragment on your files,
it should help you, although defrag maybe slow, too.
When deleting files does it matter if the data is fragmented?

Usage of balancing btrfs is "btrfs filesystem balance",
not "btrfs device balance". And remove unneeded
usage of "btrfs filesystem defrag".
Also fix some typos and over 80 columns.
