Help text

This enables the /proc/pid/seccomp_cache interface to monitor seccomp cache data. The file format is subject to change. Reading the file requires CAP_SYS_ADMIN.

This option is for debugging only. Enabling presents the risk that an adversary may be able to infer the seccomp filter logic.

If unsure, say N.
