NAME

6       balance_dirty_pages_ratelimited_nr - balance dirty memory state
7

SYNOPSIS

9       void balance_dirty_pages_ratelimited_nr(struct address_space * mapping,
10                                               unsigned long nr_pages_dirtied);
11

ARGUMENTS

13       mapping
14           address_space which was dirtied
15
16       nr_pages_dirtied
17           number of pages which the caller has just dirtied
18

DESCRIPTION

20       Processes which are dirtying memory should call in here once for each
21       page which was newly dirtied. The function will periodically check the
22       system's dirty state and will initiate writeback if needed.
23
24       On really big machines, get_writeback_state is expensive, so try to
25       avoid calling it too often (ratelimiting). But once we're over the
26       dirty memory limit we decrease the ratelimiting by a lot, to prevent
27       individual processes from overshooting the limit by (ratelimit_pages)
28       each.
