[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 0/3] Btrfs: add IO error device stats
The goal is to detect when drives start to get an increased error rate,
when drives should be replaced soon. Therefore statistic counters are
added that count IO errors (read, write and flush). Additionally, the
software detected errors like checksum errors and corrupted blocks are
counted.
An ioctl interface is added to get the device statistic counters.
A second ioctl is added to atomically get

[PATCH v1 0/2] Btrfs-progs: commands "resolve inode" and "resolve logical"
The kernel patch series just sent (Subject: "Btrfs: scrub: print path to
corrupted files and trigger nodatasum fixup") introduces two new ioctls to
do in-kernel filesystem path construction. This series provides the
corresponding userspace changes, adding two new commands to the btrfs utility:
--
btrfs resolve inode [-v] <inode> <path>
resolves an <inode> to all

[PATCH v5 0/3] Btrfs: add IO error device stats
Changes v1-v2:
- Remove restriction that BTRFS_IOC_GET_DEVICE_STATS is a privileged
operation
- Cast u64 to unsigned long long for printf()
Changes v2-v3:
- Rebased on Chris'' current master
Changes v3-v4:
- Add padding at end of ioctl structure
Changes v4-v5:
- The statistic members in the ioctl are now organized as an array of
64 bit values. Symbolic names for the array indexes

[PATCH v4 0/6] btrfs: generic readeahead interface
This series introduces a generic readahead interface for btrfs trees.
The intention is to use it to speed up scrub in a first run, but balance

by a readahead. Deletion of large files comes to mind, where the fetching
of the csums takes most of the time.

IPath infiniband support (PCI_MSI conflicts with XEN)
Hi,
I''m trying to use a QLogic ipath infiniband card with
xen. Unfortunately the ipath driver requires PCI_MSI and PCI_MSI
conflicts with xen.
Does anyone know the reason for that conflict or how hard it would be
to make it work?
MfG

[PATCH 0/4] btrfs: out-of-band (aka offline) dedupe v4
Hi,
The following series of patches implements in btrfs an ioctl to do
out-of-band deduplication of file extents.
To be clear, this means that the file system is mounted and running, but the
dedupe is not done during file writes, but after the fact when some
userspace software initiates a dedupe.
The primary patch is loosely based off of one sent by Josef Bacik back
in January, 2011.

[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] Btrfs: fix crash in scrub repair code when device is missing
Fix that when scrub tries to repair an I/O or checksum error and one of
the devices containing the mirror is missing, it crashes in bio_add_page
because the bdev is a NULL pointer for missing devices.

[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:

[patch 00/65] Error handling patchset v3
Hi all -
Here''s my current error handling patchset, against 3.1-rc8. Almost all of
this patchset is preparing for actual error handling. Before we start in
on that work, I''m trying to reduce the surface we need to worry about. It
turns out that there is a ton of code that returns an error code but never
actually reports an error.
The patchset has grown to 65 patches. 46 of them

[PATCH 1/2 v3] Btrfs: use flag EXTENT_DEFRAG for snapshot-aware defrag
We''re going to use this flag EXTENT_DEFRAG to indicate which range
belongs to defragment so that we can implement snapshow-aware defrag:
We set the EXTENT_DEFRAG flag when dirtying the extents that need
defragmented, so later on writeback thread can differentiate between
normal writeback and writeback started by defragmentation.
This patch is used for the latter one.

current bind version
Hi.
I have had an enquiry from the Network and Security guy. He wants to
know why CentOS 5.5 /RHEL 5 is using a very old version of bind
"bind-chroot-9.3.6-4.P1.el5_5.3" when the latest release that has many
security fixes is on 9.7.3 . I understand that its to maintain a known
stable platform by in introducing new elements etc .. Is there an
official explanation / document that I can

[PATCH v0 00/18] btfs: Subvolume Quota Groups
This is a first draft of a subvolume quota implementation. It is possible
to limit subvolumes and any group of subvolumes and also to track the amount
of space that will get freed when deleting snapshots.
The current version is functionally incomplete, with the main missing feature
being the initial scan and rescan of an existing filesystem.
I put some effort into writing an introduction into

[GIT PULL v3] Btrfs: improve write ahead log with sub transaction
I''ve been working to try to improve the write-ahead log''s performance,
and I found that the bottleneck addresses in the checksum items,
especially when we want to make a random write on a large file, e.g a 4G file.
Then a idea for this suggested by Chris is to use sub transaction ids and just
to log the part of inode that had changed since either the last log commit or

[PATCH] btrfs-progs: fix 32bit int/pointer cast warnings
This uses uintptr_t to cast pointers to u64 ioctl arguments to silence

[PATCH] Btrfs: add tests for find_lock_delalloc_range
So both Liu and I made huge messes of find_lock_delalloc_range trying to fix
stuff, me first by fixing extent size, then him by fixing something I broke and
then me again telling him to fix it a different way. So this is obviously a
candidate for some testing. This patch adds a pseudo fs so we can allocate fake
inodes for tests that need an inode or pages. Then it addes a bunch of tests to

[PATCH] Btrfs: fix passing wrong arg gfp_t to decide the correct allocation mode
If you look the code carefully, you will see all the tree_mod_alloc()
has to use GFP_ATOMIC. However, the original code pass the wrong arg
gfp_t in some places, this dosen''t cause any problems, because in the
tree_mod_alloc(), it ignores arg gfp_t and just use GFP_ATOMIC directly,
this is not good.
However, i think we should try best not to allocate with GFP_ATOMIC, so
i keep the gfp_t
