Hello, I just noticed an error in the current version of Klaus-Peter Junghanns bristuff package, especially in the HFC module. Everytime I try to unload the HFC module with "modprobe -r" I got a kernel panic and the complete server hangs up so I need to do a hard reset. Regards, Julian Pawlowski

This version fixes three bugs in the 2nd patch of this series that caused kernel BUG when the system was under race. We weren't accounting with t_oustanding_credits correctly, and there were race conditions caused by the fact the I had overlooked the fact that __jbd2_log_wait_for_space() and jbd2_get_transaction() requires j_state_lock to be write locked.

Hi Chris, This is the extent of my current queue of Btrfs snapshot/subvol/commit stuff. Most of these were posted several months ago. Can be sent upstream during this merge window? Not having this functionality is becoming a bit of a roadblock for our efforts to keep the Ceph data in a consistent state. These patches are also available from
