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.
