Hi,
we test on kernel 4.19.0 on android, after run more than 24 Hours monkey
stress test, we see OOM on 1/10 2G memory board, the issue is not seen on the
4.14 kernel.
we have done some debugs:
1. OOM is due to the filp consume too many memory: 300M vs 2G board.
2. with the 120s hung task
Hi,
I submit the patch based on tag v4.19.

The patch I submitted is based on the latest kernel,
I checked the latest kernel has the same logic,
so I send the patch to LKML.

Thanks, Greg.
I did use this patch to fix many races on SMP. But to respect maintainer, I
stop pushing the patch to upstream.

We often hit kernel panic issues on SMP machines because processes race
on multiple cpu. By adding a new parameter printk.cpu, kernel prints
cpu number at printk information line. It’s useful to debug what cpus
are racing.

imer callback fn, another thread might call enqueue_hrtimer or
hrtimer_start
to requeue it, and the timer->state is equal to
HRTIMER_STATE_CALLBACK|HRTIMER_STATE_ENQUEUED,
which causes the BUG_ON(timer->state != HRTIMER_STATE_CALLBACK) checking fails.
The patch fixes it by checking only bit HRTI
