Subject: Re: [PATCH 2/4] Task notifier against mm: Implement todo list in task_struct

Hi!

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 13
EXTRAVERSION =-rc3-mm3
This patch fails:
pavel@amd:/usr/src/linux-mm$ cat /tmp/delme | patch -Esp1
1 out of 3 hunks FAILED -- saving rejects to file include/linux/sched.h.rej
pavel@amd:/usr/src/linux-mm$
No wonder when -mm already contains:
/*
* Check if there is a request to freeze a process
*/
static inline int freezing(struct task_struct *p)
{
return test_ti_thread_flag(p->thread_info, TIF_FREEZE);
}
