writeback: disable periodic old data writeback for !dirty_writeback_centisecs
commit 69b62d01ec44fe0d505d89917392347732135a4d upstream.
Prior to 2.6.32, setting /proc/sys/vm/dirty_writeback_centisecs disabled
periodic dirty writeback from kupdate. This got broken and now causes
excessive sys CPU usage if set to zero, as we'll keep beating on
schedule().
