Enables the display of the minimum amount of free stack which each

task has ever had available in the sysrq-T and sysrq-P debug output.

This option will slow down process creation somewhat.

Kprobes allows you to trap at almost any kernel address and
|
||
|
|
execute a callback function. register_kprobe() establishes
|
||
|
|
a probepoint and specifies the callback. Kprobes is useful
|
||
|
|
for kernel debugging, non-intrusive instrumentation and testing.
|
||
|
|
If in doubt, say "N".
