...though - the currently specified API makes transaction inherently inefficient I think. If we *just* want to provide a way to specify an atomic grouping, we could modify the API to allow such transactions with a minimal overhead like so: * Remove cancel_transaction * Rename commit_transaction to end_transaction * flush is deemed as invalid (or ignored) when in a transaction * begin_transaction sets an "in_transaction" flag * if "in_transaction" is set, we don't autoflush * (Possibly) if we're close to autoflushing already, begin_transaction could autoflush The only lo...

The freeze rwsem is taken by sb_start_intwrite() and dropped during the commit_ or end_transaction(). In the async case, that happens in a worker thread. Tell lockdep the calling thread is releasing ownership of the rwsem and the async thread is picking it up. Josef and I worked out a more complicated solution that made the async commit thread join and potentially get a later transaction,...

...additional days to gather. Thanks, Arne Arne Jansen (18): btrfs: mark delayed refs as for cow btrfs: always save ref_root in delayed refs btrfs: add nested locking mode for paths btrfs: qgroup on-disk format btrfs: add helper for tree enumeration btrfs: check the root passed to btrfs_end_transaction btrfs: generic data structure to build unique lists btrfs: added helper to create new trees btrfs: qgroup state and initialization btrfs: Test code to change the order of delayed-ref processing btrfs: add sequence numbers to delayed refs btrfs: put back delayed refs that are too new...
