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---
|
|
Enabling this option turns a certain set of sanity checks for user
|
|
copy operations into compile time failures.
|
|
|
|
The copy_from_user() etc checks are there to help test if there
|
|
are sufficient security checks on the length argument of
|
|
the copy operation, by having gcc prove that the argument is
|
|
within bounds.
|
|
|
|
If unsure, or if you run an older (pre 4.4) gcc, say N.
