node
.RS 4
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\&.
.RE
.PP
_softexpires
.RS 4
the absolute earliest expiry time of the hrtimer\&. The time which was given as expiry time when the timer was armed\&.
.RE
.PP
function
.RS 4
timer expiry callback function
.RE
.PP
base
.RS 4
pointer to the timer base (per cpu and per clock)
.RE
.PP
state
.RS 4
state information (See bit values above)
.RE

is_rel
.RS 4
Set if the timer was armed relative

start_pid
.RS 4
timer statistics field to store the pid of the task which started the timer
.RE

start_site
.RS 4
timer statistics field to store the site where the timer was started
.RE
