Roland McGrath de328e684f 2008-05-19 Roland McGrath <roland@redhat.com> 
* time.c (sys_timerfd_create): New function.
	(sys_timerfd_settime, sys_timerfd_gettime): New functions.
	* linux/syscall.h: Declare them.
	* linux/syscallent.h: Update entries for those syscalls.
	From Kyle McMartin <kyle@mcmartin.ca>.
