Niltze [Hello], Thomas-
FYI
Starting from Linux kernel 4.14.18, arch/x86/include/asm/thread_info.h
adds an extra line of code that affects your patch --included in
Debian kernel packaging for Linux 4.14.17 / 4.15.4:
debian/patches/features/all/rt/x86-preempt-lazy.patch
i.e.,
...
struct task_struct;
#include <asm/cpufeature.h>
#include <linux/atomic.h>
struct thread_info {
unsigned long flags; /* low level flags */
u32 status; /* thread synchronous flags */
...
When Debian packaging applies the RT patch with fuzz=0, it fails.
Accordingly, I edited your patch (attached) for it to apply (fuzz=0)
to my subject Debian kernel -- *assuming* the RT kernel version will
want to keep the new line of code.
Best Professional Regards.
