| D | balance.rst | 17 the caller may also wish to avoid waking kswapd.
66 problems: first, kswapd is woken up as in 2.2 on low memory conditions
74 kswapd also needs to know about the zones it should balance. kswapd is
77 and all process contexts are sleeping. For 2.3, kswapd does not really
79 highmem pages. kswapd looks at the zone_wake_kswapd field in the zone
92 Orthogonal to this, is the decision to poke kswapd to free some zone pages.

946 amount of memory left in a node/system before kswapd is woken up and
947 how much memory needs to be free before kswapd goes back to sleep.
