[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] Btrfs: fix broken nocow after balance
Balance will create reloc_root for each fs root, and it''s going to
record last_snapshot to filter shared blocks. The side effect of
setting last_snapshot is to break nocow attributes of files.
So it turns out that checking last_snapshot does not always ensure that
a node/leaf/file_extent is shared.
That''s why shared node/leaf needs to search extent tree for number of

[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:

[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 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
is another hot candidate. In general, every tree walk could be accompanied
by a readahead. Deletion of large files comes to mind, where the fetching
of the csums takes most of the time.
Also the initial build-ups of free-space-caches and
