Jan Kara 41617e1a8d jbd2: add support for avoiding data writes during transaction commits ... Currently when filesystem needs to make sure data is on permanent storage before committing a transaction it adds inode to transaction's inode list. During transaction commit, jbd2 writes back all dirty buffers that have allocated underlying blocks and waits for the IO to finish. However when doing writeback for delayed allocated data, we allocate blocks and immediately submit the data. Thus asking jbd2 to write dirty pages just unnecessarily adds more work to jbd2 possibly writing back other redirtied blocks. Add support to jbd2 to allow filesystem to ask jbd2 to only wait for outstanding data writes before committing a transaction and thus avoid unnecessary writes.
