[PATCH v3 1/3] asm-generic: Add generic seccomp.h for secure computing mode 1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Those values (__NR_seccomp_*) are used solely in secure_computing()
to identify mode 1 system calls. If compat system calls have different
syscall numbers, asm/seccomp.h may override them.
