Description: Kernel Samepage Merging daemon sysfs interface
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.
See Documentation/vm/ksm.rst for more information.
What: /sys/kernel/mm/ksm/merge_across_nodes
Date: January 2013
KernelVersion: 3.9
Contact: Linux memory management mailing list <linux-mm@kvack.org>
Description: Control merging pages across different NUMA nodes.
When it is set to 0 only pages from the same node are merged,
otherwise pages from all nodes can be merged together (default).
