struct interrupt_frame	frame
	Frame pushed during the last userland -> kernel context switch.
pid_t	tid

node_t	this
union {
struct {
clock_t   preempt
	End of the currently running thread's timeslice.
}   running
	For running threads only.
struct {
clock_t   wakeup
}   sleep
	For sleeping threads only.
};
	Information relative to the current state of the thread.

Detailed Description

The struct contains information about the thread's execution state. This state is architecture dependant, so its actual definition is present inside the arch specific process header file.

Generic information about a thread include its current state (used by the scheduler), information about its containing process and feature flags.
