kmemtrace.txt question: kernel parameter(s)?

[Randy Dunlap]

Hi,

Documentation/trace/kmemtrace.txt says:

Q: 'cat /sys/kernel/debug/kmemtrace/total_overruns' is non-zero, how do I fix
this? Should I worry?
A: If it's non-zero, this affects kmemtrace's accuracy, depending on how
large the number is. You can fix it by supplying a higher
'kmemtrace.subbufs=N' kernel parameter.


Where is this kernel parameter implemented and where is it documented?
or should this Answer just be fixed?


thanks,
