9 Enables the display of the minimum amount of free stack which each
10 task has ever had available in the sysrq-T and sysrq-P debug output.
12 This option will slow down process creation somewhat.

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