From c289b074b66e2e59c65aba73f40b99e797e92d2f Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Fri, 1 Feb 2008 20:41:30 +0300 Subject: hrtimer: don't modify restart_block->fn in restart functions hrtimer_nanosleep_restart() clears/restores restart_block->fn. This is pointless and complicates its usage. Note that if sys_restart_syscall() doesn't actually happen, we have a bogus "pending" restart->fn anyway, this is harmless.
