Dbalance.rst17 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

92 Orthogonal to this, is the decision to poke kswapd to free some zone pages.

Dvm.rst912 This factor controls the aggressiveness of kswapd. It defines the
913 amount of memory left in a node/system before kswapd is woken up and
914 how much memory needs to be free before kswapd goes back to sleep.
