dynamic_emit_prefix
SYSCALL_DEFINE1
wait_task_zombie	Handle sys_wait4 work for one task in state EXIT_ZOMBIE. We hold* read_lock(&tasklist_lock) on entry. If we return zero, we still hold* the lock and this task is uninteresting. If we return nonzero, we have
wait_task_stopped	wait_task_stopped - Wait for %TASK_STOPPED or %TASK_TRACED@wo: wait options@ptrace: is the wait for ptrace@p: task to wait for Handle sys_wait4() work for %p in state %TASK_STOPPED or %TASK_TRACED
wait_task_continued	Handle do_wait work for one task in a live, non-stopped state.* read_lock(&tasklist_lock) on entry. If we return zero, we still hold* the lock and this task is uninteresting. If we return nonzero, we have
kill_something_info	kill_something_info() interprets pid in interesting ways just like kill(2).* POSIX specifies that kill(-1,sig) is unspecified, but what we have* is probably wrong. Should make it like BSD or SYSV.
ptrace_do_notify
ptrace_signal
do_rt_sigqueueinfo
do_rt_tgsigqueueinfo
SYSCALL_DEFINE3
SYSCALL_DEFINE2	Ugh. To avoid negative return values, "getpriority()" will* not return the normal nice-value, but a negated value that* has been offset by 20 (ie it returns 40..1 instead of -20..19)* to stay compatible.
sys_gettid
SYSCALL_DEFINE2	This needs some heavy checking
schedule_tail	schedule_tail - first thing a freshly forked thread must call.*@prev: the thread we just switched away from.
posix_cpu_nsleep
attach_to_pi_state	Validate that the existing waiter has a pi_state and sanity check* the pi_state against the user space value. If correct, attach to* it.
futex_lock_pi_atomic	ex_lock_pi_atomic() - Atomic work required to acquire a pi aware futex@uaddr: the pi futex user address@hb: the pi futex hash bucket@key: the futex key associated with uaddr and hb@ps: the pi_state pointer where we store the result of the* lookup
wake_futex_pi	Caller must hold a reference on @pi_state.
futex_proxy_trylock_atomic	ex_proxy_trylock_atomic() - Attempt an atomic lock for the top waiter@pifutex: the user address of the to futex@hb1: the from futex hash bucket, must be locked by the caller@hb2: the to futex hash bucket, must be locked by the caller@key1: the from
fixup_pi_state_owner
futex_unlock_pi	Userspace attempted a TID -> 0 atomic transition, and failed.* This is the in-kernel slowpath: we look up the PI state (if any),* and do the rt-mutex unlock.
handle_futex_death	Process a futex-list entry, check whether it's owned by the* dying task, and do notification if so:
cgroup_procs_show
pidlist_array_load	Load a cgroup's pidarray with either procs' tgids or tasks' pids
cgroup_css_links_read
SYSCALL_DEFINE3
SYSCALL_DEFINE2
userfault_msg
format_corename	rmat_corename will inspect the pattern parameter, and output a* name into corename, which must have space for at least* CORENAME_MAX_SIZE bytes plus one byte for the zero terminator.
