The stack direction will be * determined by the kernel and set up * appropriately based on @stack_size. * @stack_size: The size of the stack for the child process. * @tls: If CLONE_SETTLS is set, the tls descriptor * is set to tls. * @set_tid: Pointer to an array of type *pid_t. The size * of the array is defined using @set_tid_size. * This array is used to select PIDs/TIDs for * newly created processes. The first element in * this defines the PID in the most nested PID * namespace. Each additional element in the array * defines the PID in the parent PID namespace of * the original PID namespace. If the array has * less entries than the number of currently * nested PID namespaces only the PIDs in the * corresponding namespaces are set. * @set_tid_size: This defines the size of the array referenced * in @set_tid. This cannot be larger than the * kernel's limit of nested PID namespaces. * @cgroup: If CLONE_INTO_CGROUP is specified set this to * a file descriptor for the cgroup. * * The structure is versioned by size and thus extensible. * New struct members must go at the end of the struct and * must be properly 64bit aligned. */ struct clone_args { … }; #endif #define CLONE_ARGS_SIZE_VER0 … #define CLONE_ARGS_SIZE_VER1 … #define CLONE_ARGS_SIZE_VER2 … /* * Scheduling policies */ #define SCHED_NORMAL … #define SCHED_FIFO … #define SCHED_RR … #define SCHED_BATCH … /* SCHED_ISO: reserved but not implemented yet */ #define SCHED_IDLE … #define SCHED_DEADLINE … /* Can be ORed in to make sure the process is reverted back to SCHED_NORMAL on fork */ #define SCHED_RESET_ON_FORK … /* * For the sched_{set,get}attr() calls */ #define SCHED_FLAG_RESET_ON_FORK … #define SCHED_FLAG_RECLAIM … #define SCHED_FLAG_DL_OVERRUN … #define SCHED_FLAG_KEEP_POLICY … #define SCHED_FLAG_KEEP_PARAMS … #define SCHED_FLAG_UTIL_CLAMP_MIN … #define SCHED_FLAG_UTIL_CLAMP_MAX … #define SCHED_FLAG_KEEP_ALL … #define SCHED_FLAG_UTIL_CLAMP … #define SCHED_FLAG_ALL … #endif /* _UAPI_LINUX_SCHED_H */
