Hi all,
After merging the header_cleanup tree, today's linux-next build (s390
defconfig) failed like this:
arch/s390/kernel/signal.c: In function 'arch_do_signal_or_restart':
arch/s390/kernel/signal.c:491:17: error: implicit declaration of function 'rseq_signal_deliver' [-Werror=implicit-function-declaration]
491 | rseq_signal_deliver(&ksig, regs);
| ^~~~~~~~~~~~~~~~~~~
Presumably caused by commit
cd1146fc0ad3 ("rseq: Split out rseq.h from sched.h")
I have applied the following patch for today:
From: Stephen Rothwell <[email protected]>

Subject: [PATCH] fixup for s390 and "rseq: Split out rseq.h from sched.h"

I've applied the same fixup to my tree.
