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.
