For this scenario: server crashes (could be because a table is corrupted) and Recovery repeatedly crashes on this table. User repairs it with maria_chk (as REPAIR TABLE is not possible), restarts the server, Recovery runs: for Recovery to not apply old REDOs to this repaired table (which would fail: rows have moved), maria_chk sets create_rename_lsn to the max value. Later when the server opens the table via ha_maria, it sets the LSN to the correct current value. storage/maria/ma_check.c: using helper function storage/maria/ma_create.c: A new helper function which stores the create_rename_lsn into the table's header on disk when we cannot wait for this to happen naturally at a later _ma_state_info_write(). storage/maria/ma_delete_all.c: using helper function; so log_data now can be FILEID_STORE_SIZE. storage/maria/ma_open.c: When opening a transactional table in the server, we discover if it has been repaired with maria_chk and if yes, give it a correct create_rename_lsn. storage/maria/ma_rename.c: using helper function storage/maria/maria_chk.c: By setting create_rename_lsn to the maximum possible LSN, maria_chk ensures that old REDOs are not applied to the new table it is going to produce. storage/maria/maria_def.h: new helper function
