    Subject[PATCH 1/8] mm: export dirty_writeback_interval
    Date
    From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

    Export 'dirty_writeback_interval' to make it visible to file-systems. We are
    going to push superblock management down to file-systems and get rid of the
    'sync_supers' kernel thread completly.
