commit d9a3c9823a2e6a543eb7807fb3d15d8233817ec5 upstream.
Backported for 3.9-stable. Minor context adjustment.
You forgot to fix the build error that this patch causes, which makes me
think you didn't build it:
kernel/sched/cputime.c: In function ‘scale_stime’:
kernel/sched/cputime.c:539:3: error: implicit declaration of function
‘div64_u64_rem’ [-Werror=implicit-function-declaration]
I've dropped all 4 of these from my queue, please fix up, and test,
before resending them.
I did build the patch series on x86_64 and i386. I suppose you built
with only the first patch applied?
Indeed the first patch,
sched: Lower chances of cputime scaling overflow
adds the undefined div64_u64_rem, which is promptly reverted in the
second patch,
sched: Avoid cputime scaling overflow
Is it broken this way in Linus's tree?
I stand corrected. I should have tested with each patch instead of the
whole patch series. I will do better next time.
As Stanislaw offers to backport this, mine can be dropped.
