From be5dad20a55e054a35dac7f6f5f184dc72b379b4 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 31 Aug 2008 08:19:15 -0700 Subject: [PATCH] select: add a poll specific struct to the restart_block union with hrtimer poll/select, the signal restart data no longer is a single long representing a jiffies count, but it becomes a second/nanosecond pair that also needs to encode if there was a timeout at all or not. This patch adds a struct to the restart_block union for this purpose Signed-off-by: Thomas Gleixner Signed-off-by: Arjan van de Ven --- include/linux/thread_info.h | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/include/linux/thread_info.h b/include/linux/thread_info.h index 38a56477f27..e6b820f8b56 100644 --- a/include/linux/thread_info.h +++ b/include/linux/thread_info.h @@ -38,6 +38,14 @@ struct restart_block { #endif u64 expires; } nanosleep; + /* For poll */ + struct { + struct pollfd __user *ufds; + int nfds; + int has_timeout; + unsigned long tv_sec; + unsigned long tv_nsec; + } poll; }; }; -- 2.11.4.GIT
