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

For quite a while, I''ve experienced oddities with snapshotted Firefox _CACHE_00?_ files, whose checksums (and contents) would change after the btrfs snapshot was taken, and would even change depending on how the file was brought to memory (e.g., rsyncing it to backup storage vs checking its md5sum before or after the rsync). This only affected these cache files, so I didn''t give
