full_scans: how many times all mergeable areas have been
|
|
scanned.
|
|
|
|
pages_shared: how many shared pages are being used.
|
|
|
|
pages_sharing: how many more sites are sharing them i.e. how
|
|
much saved.
|
|
|
|
pages_to_scan: how many present pages to scan before ksmd goes
|
|
to sleep.
|
|
|
|
pages_unshared: how many pages unique but repeatedly checked
|
|
for merging.
|
|
|
|
pages_volatile: how many pages changing too fast to be placed
|
|
in a tree.
|
|
|
|
run: write 0 to disable ksm, read 0 while ksm is disabled.
|
|
|
|
- write 1 to run ksm, read 1 while ksm is running.
|
|
- write 2 to disable ksm and unmerge all its pages.
|
|
|
|
sleep_millisecs: how many milliseconds ksm should sleep between
|
|
scans.

When it is set to 0 only pages from the same node are merged,
|
|
otherwise pages from all nodes can be merged together (default).
