I have asked
I'm thinking of a way to debug this too. The symptom may hint at a
use-after-free. Could you enable KASAN in your tests? (On the flip

I observed hard reproductible the set of bugs.
It always started as

Hi folks.
While testing 5.8 RCs I founded that kernel log flooded by the message
"WARNING: CPU: 28 PID: 211236 at fs/fuse/file.c:1684 tree
insert+0xaf/0xc0 [fuse]" when I start podman container.
In kernel 5.7 not has such a problem.

Hi folks.
Yesterday I updated kernel to 5.2 (git commit 7e9890a3500d)
I always leave computer working at night.
Today at morning I am found that computer are hanged.
I was connect via ssh and look at kernel log.
There I had seen strange records which I never seen before:
