Help text

Enable this to turn on some debug checking for credential management. The additional code keeps track of the number of pointers from task_structs to any given cred struct, and checks to see that this number never exceeds the usage count of the cred struct.

Furthermore, if SELinux is enabled, this also checks that the security pointer in the cred struct is never seen to be invalid.

If unsure, say N.
