.SH "DESCRIPTION"
.PP
Processes which are dirtying memory should call in here once for each page which was newly dirtied\&. The function will periodically check the system\*(Aqs dirty state and will initiate writeback if needed\&.
.PP
On really big machines, get_writeback_state is expensive, so try to avoid calling it too often (ratelimiting)\&. But once we\*(Aqre over the dirty memory limit we decrease the ratelimiting by a lot, to prevent individual processes from overshooting the limit by (ratelimit_pages) each\&.
