ext4: fast commit API cleanup This patch series fixes up fast commit APIs. There are NO on-disk format changes introduced in this series. The main contribution of the series is that it drops fast commit specific transaction APIs and makes fast commits work with journal transaction APIs of JBD2 journalling system. With these changes, a fast commit eligible transaction is simply enclosed in calls to "jbd2_journal_start()" and "jbd2_journal_stop()". If the update that is being performed is fast commit ineligible, one must simply call ext4_fc_mark_ineligible() after starting a transaction using "jbd2_journal_start()". The last patch in the series simplifies fast commit stats recording by moving it to a different function. I verified that the patch series introduces no regressions in "quick" and "log" groups when "fast_commit" feature is enabled.
