"dirty writeback" frequency to save power

[Flavio Costa]

Maybe if you insert 'sys.vm.dirty_writeback_centisecs = 1500' in
'/etc/sysctl.conf' you can obtain the result you want.
The value will not change as soon as you save the file you can either reboot
your machine or execute this command 'sysctl -p'
