[PATCH 00/11] Btrfs: some patches for 3.3
The biggest one is a fix for fstrim, and there''s a fix for on-disk
free space cache. Others are small fixes and cleanups.
The last three have been sent weeks ago.
The patchset is also available in this repo:
git://repo.or.cz/linux-btrfs-devel.git for-chris
Note there''s a small confict with Al Viro''s vfs changes.

[PATCH 00/21] [RFC] Btrfs: restriper
Hello,
This patch series adds an initial implementation of restriper (it''s a
clever name for relocation framework that allows to do selective profile
changing and selective balancing with some goodies like pausing/resuming
and reporting progress to the user.
Profile changing is global (per-FS) so far, per-subvolume profiles
require some discussion and can be implemented in future.

[PATCH v3 0/3] btrfs: quasi-round-robin for chunk allocation
In a multi device setup, the chunk allocator currently always allocates
chunks on the devices in the same order. This leads to a very uneven
distribution, especially with RAID1 or RAID10 and an uneven number of
devices.
This patch always sorts the devices before allocating, and allocates the
stripes on the devices with the most available space, as long as there
is enough space available. In a low

“bio too big” regression and silent data corruption in 3.0
tl;dr version: 3.0 produces “bio too big” dmesg entries and silently
corrupts data in “meta-raid1/data-single” configurations on disks with
different max_hw_sectors, where 2.6.38 worked fine.
tl;dr side-issue: on-line removal of partitions holding “single” data
attempts to create raid0 (rather than single) block groups. If it can''t
get enough room for raid0 over all remaining disks, it

[PATCH 0/3] Btrfs-progs: restriper interface
Hello,
This is the userspace part of restriper, rebased onto the new progs
infrastructure. Restriper commands are located under ''balance'' prefix,
which is now the top level command group. However to not confuse
existing users ''balance'' prefix is also available under ''filesystem'':

[PATCH][BTRFS-PROGS][V3] btrfs filesystem df
Hi Chris,
this serie of patches updated the command "btrfs filesystem
df". I update this command because it is not so easy to get
the information about the disk usage from the command "fi df" and "fi show".
This patch was the result of some discussions on the btrfs
mailing list. Many thanks to all the contributors.
From the man page (see 2nd patch):

[PATCH 0 of 3 v2] PV-GRUB: add support for ext4 and btrfs
Hi,
The following patches add support for ext4 and btrfs to
PV-GRUB. These patches are taken nearly verbatim from those provided
by Fedora and Gentoo.
We''ve been using these patches for the PV-GRUB images available in EC2
for some time now with no problems.
Changes from v1:
- Makefile has been changed to check the exit code from patch
- The btrfs patch has been rebased to apply

[PATCH v1 0/6] btrfs: scrub
This series adds an initial implementation for scrub. It works quite
straightforward. The usermode issues an ioctl for each device in the
fs. For each device, it enumerates the allocated device chunks. For
each chunk, the contained extents are enumerated and the data checksums
fetched. The extents are read sequentially and the checksums verified.
If an error occurs (checksum or EIO), a good copy

[PATCH v5 0/8] Btrfs scrub: print path to corrupted files and trigger nodatasum fixup
While testing raid-auto-repair patches I''m going to send out later, I just found
the very last bug in my current scrub patch series:
Changelog v4->v5:
- fixed a deadlock when fixup is taking longer while scrub is about to end
Original message follows:
------------------------
This patch set introduces two new features for scrub. They share the backref
iteration code which is the
