Hi guys, my computer suddenly failed to boot. It seams that it is unable to mount /home which is btrfs. Here are the messages I get during the boot (the relevant part; hopefully): Feb 02 13:59:58 Edge kernel: kernel BUG at fs/btrfs/extent-tree.c:6185!

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

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 the last

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
