Hello everyone,
Since doing the initial Btrfs benchmarks, I've made my blktrace graphing
utility a little more generic and tossed it out on oss.oracle.com.
This new version can easily graph two different runs, and has a few
other tweaks that make the graphs look nicer.

Hello everyone,
I've tossed out seekwatcher v0.3. The major changes are using rolling
averages to smooth out the seek and throughput graphs, and it can
generate mpgs of the IO done by a given trace.
Here's a sample of the smoother graphs (creating 20 kernel trees):

Hello everyone,
I'm stealing the cc list and reviving and old thread because I've
finally got some numbers to go along with the Btrfs variable blocksize
feature. The basic idea is to create a read/write interface to
map a range of bytes on the address space, and use it in Btrfs for all
metadata

Hi Linus
My for-linus branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
Has a recent fix from Josef for our tree log replay code. It fixes
problems where the inode counter for the number of bytes in the file
wasn't getting updated properly during fsync
offset for compressed extents

I'll run some tests here. My original patch is below (it's slightly
different from Muthu's).
Btrfs is sometimes calling bio_endio twice on the same bio while
we chain things. This makes sure we don't trip over new assertions in
fs/bio.c

Ok, Kent did pull in one of my hunks, one was a comment and the third
was effectively the same as your patch. I tried to test the end result
today, but get these on

Hi Linus,
We've got more bug fixes in my for-linus branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
One of these fixes another corner of the compression oops from last
time. Miao nailed down some problems with concurrent snapshot deletion
and drive

Please pull my for-linus branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
These are mostly bug fixes and a two small performance fixes. The most
important of the bunch are Josef's fix for a snapshotting regression and
Mark's update to fix compile
