From e4ecda1b60bfd2333c12bbe71b153d3b6bdc831a Mon Sep 17 00:00:00 2001 From: Mark Lord Date: Sat, 25 Sep 2010 11:17:22 +0200 Subject: [PATCH] Fix compile error in blk-exec.c for !CONFIG_DETECT_HUNG_TASK Ensure that 'sysctl_hung_task_timeout_secs' is defined even when CONFIG_DETECT_HUNG_TASK is not set. This way we can safely reference it without need for ifdefs in the code elsewhere. eg. in block/blk-exec.c Signed-off-by: Mark Lord Signed-off-by: Jens Axboe --- include/linux/sched.h | 3 +++ 1 file changed, 3 insertions(+) diff --git a/include/linux/sched.h b/include/linux/sched.h index 1e2a6db2d7dd..dbafa9e34a2d 100644 --- a/include/linux/sched.h +++ b/include/linux/sched.h @@ -336,6 +336,9 @@ extern unsigned long sysctl_hung_task_warnings; extern int proc_dohung_task_timeout_secs(struct ctl_table *table, int write, void __user *buffer, size_t *lenp, loff_t *ppos); +#else +/* Avoid need for ifdefs elsewhere in the code */ +enum { sysctl_hung_task_timeout_secs = 0 }; #endif /* Attach to any functions which should be ignored in wchan output. */ -- 2.45.2
