BALANCE_DIRTY_PAGES_(9) Memory Management in Linux BALANCE_DIRTY_PAGES_(9)
NAME
balance_dirty_pages_ratelimited - balance dirty memory state
SYNOPSIS
void balance_dirty_pages_ratelimited(struct address_space * mapping);
ARGUMENTS
mapping
address_space which was dirtied
DESCRIPTION
Processes which are dirtying memory should call in here once for each page which was newly
dirtied. The function will periodically check the system's dirty state and will initiate
writeback if needed.
On really big machines, get_writeback_state is expensive, so try to avoid calling it too
often (ratelimiting). But once we're over the dirty memory limit we decrease the
ratelimiting by a lot, to prevent individual processes from overshooting the limit by
(ratelimit_pages) each.
