off - disable kmemleak (irreversible)
stack=on - enable the task stacks scanning
stack=on - enable the task stacks scanning (default)
stack=off - disable the tasks stacks scanning
scan=on - start the automatic memory scanning thread
scan=on - start the automatic memory scanning thread (default)
scan=off - stop the automatic memory scanning thread
scan=<secs> - set the automatic memory scanning period in seconds (0
to disable it)
scan=<secs> - set the automatic memory scanning period in seconds
(default 600, 0 to stop the automatic scanning)
Kmemleak can also be disabled at boot-time by passing "kmemleak=off" on
the kernel command line.
