struct hrtimer — the basic hrtimer structure
struct hrtimer {
struct timerqueue_node node;
ktime_t _softexpires;
enum hrtimer_restart (* function) (struct hrtimer *);
struct hrtimer_clock_base * base;
unsigned long state;
#ifdef CONFIG_TIMER_STATS
int start_pid;
void * start_site;
char start_comm[16];
#endif
}; timerqueue node, which also manages node.expires, the absolute expiry time in the hrtimers internal representation. The time is related to the clock on which the timer is based. Is setup by adding slack to the _softexpires value. For non range timers identical to _softexpires.
the absolute earliest expiry time of the hrtimer. The time which was given as expiry time when the timer was armed.
timer expiry callback function
pointer to the timer base (per cpu and per clock)
state information (See bit values above)
timer statistics field to store the pid of the task which started the timer
timer statistics field to store the site where the timer was started
timer statistics field to store the name of the process which started the timer
