1. etzion asked about controlling the age of dirty pages before pdflush
flushes them - the default value is 30 seconds, and can be seen by:
cat /proc/sys/vm/dirty_expire_centisecs
(the time there is in milli-seconds). it can be changed by echoing
the desired time into that file,
someone reminded me about the small trail through the linux kernel
link i mentioned. it is:
http://www.win.tue.nl/~aeb/linux/vfs/trail.html
note that it is from 2001 and relates to kernel 2.4 (or even older) -
but the general has not completely changed.
you can find a more up-to-date info
