From 717835d94d3e3d343a302df0a3cb9405887c3e2a Mon Sep 17 00:00:00 2001 From: Oleg Nesterov <oleg@tv-sign.ru> Date: Mon, 22 Sep 2008 14:42:49 -0700 Subject: [PATCH] posix-timers: move the initialization of timer->sigq from send to create path posix_timer_event() always populates timer->sigq with the same numbers, move this code into sys_timer_create(). Note that with this patch we can kill it_sigev_signo and it_sigev_value.
