Just a quick update, I''ve dropped the hashing stuff in favor of doing a memcmp in the kernel to make sure the data is still the same. The thing that takes a while is reading the data up from disk, so doing a memcmp of the entire buffer isn''t that big of a deal, not to mention there''s a possiblity for malicious users if there is a problem with the hashing algorithms we

Hello everybody, I've my Gentoo's /usr/portage on a loopback btrfs. Just wanted to sync and got an oops. I've a rsync and a ls process in status D now. The system has been in suspend (tuxonice 3.0-rc3) with mounted btrfs, perhaps that is related?

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

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

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. Originally patch

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the
