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.

help
|

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".

Unmap pages from the kernel linear mapping after free_pages().
|
|
This results in a large slowdown, but helps to find certain types
|
|
of memory corruptions.
