This patch - Adds a mechanism for queuing up journal entries prior to the journal being started, which will be used for early journal log messages - Adds bch2_fs_log_msg() and improves bch2_trans_log_msg(), which now take format strings. bch2_fs_log_msg() can be used before or after the journal has been started, and will use the appropriate mechanism. - Deletes the now obsolete bch2_journal_log_msg() - And adds more log messages to the recovery path - messages for journal/filesystem started, journal entries being blacklisted, and journal replay starting/finishing.
