Make that the internal values for:
/proc/sys/vm/dirty_writeback_centisecs
/proc/sys/vm/dirty_expire_centisecs
are stored as jiffies instead of centiseconds. Let the sysctl interface do
the conversions with full precision using clock_t_to_jiffies, instead of
doing overflow-sensitive on-the-fly conversions every time the values are
used.

Bart,
You forgot to fix the comments. The attached patch fixes them.
Thanks, well spotted. I think the other patch already went into Linus'
tree, I guess this should go in there as well?
Cheers,
Bart
