In linux kernel since version 2.6.32 (release Date: 2009-12-02)  
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

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.
