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.

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

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

Hi all - The following 9 patches add more error handling to the btrfs code: - Add btrfs_panic - Catch locking failures in {set,clear}_extent_bit - Push up set_extent_bit errors to callers - Push up lock_extent errors to callers - Push up clear_extent_bit errors to callers - Push up unlock_extent errors to callers - Make pin_down_extent return void - Push up btrfs_pin_extent errors to

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
