13 Enables the display of the minimum amount of free stack which each
14 task has ever had available in the sysrq-T and sysrq-P debug output.

34 bool "Strict copy size checks"
35 depends on DEBUG_KERNEL && !TRACE_BRANCH_PROFILING
37 Enabling this option turns a certain set of sanity checks for user
38 copy operations into compile time failures.
40 The copy_from_user() etc checks are there to help test if there
41 are sufficient security checks on the length argument of
42 the copy operation, by having gcc prove that the argument is
45 If unsure, or if you run an older (pre 4.4) gcc, say N.
