fs/mpage.c: forgotten WRITE_SYNC in case of data integrity write
In case of wbc->sync_mode == WB_SYNC_ALL we need to do data integrity write, thus mark request as WRITE_SYNC. akpm: afaict this change will cause the data integrity write bios to be placed onto the second queue in cfq_io_cq.cfqq[], which presumably results in special treatment. The documentation for REQ_SYNC is horrid.
