proc.5: Document /proc/sys/vm/compact_memory
...
Since 2.6.36 [1] CONFIG_COMPACTION is supported in Linux (for a
detailed explanation see [2]). But in essence the contents of
/proc/buddyinfo shows how much contiguous areas of a certain
size are available. These numbers are not actually up to date
as the Linux kernel will implicitly trigger compaction
(+- defragmentation) when an allocation is done. This makes it
difficult since you can't predict upfront whether or not a large
allocation will succeed or not. By using
/proc/sys/vm/compact_memory you can explicitly trigger compaction
to occur and /proc/buddyinfo will give a more realistic view on
the available memory in contiguous areas.
This patch updates proc.5 to explain the usage of this file and is
inspired by Documentation/systcl/vm.txt [3]
