Hello!
Using fuse-overlayfs on tmpfs (/dev/shm/[folder]) causing system to freeze during suspend / resume cycle. With kernel message:

Steps to reproduce:
mkdir -p /dev/shm/test/up mkdir -p /dev/shm/test/tmp mkdir -p /dev/shm/test/data fuse-overlayfs -o "static_nlink,noacl,upperdir=/dev/shm/test/up,lowerdir=$HOME/.mozilla/firefox/,workdir=/dev/shm/test/tmp" /dev/shm/test/data firefox --profile /dev/shm/test/data/c9933.default
Start youtube music video. Then:
systemctl suspend
Anyone can fail from the list:
Full logs:
My full firefox profile tmpfs daemon:
EDIT: starting firefox from tmpfs or dev/shm does not cause system to freeze:
cp -r ~/.mozilla/firefox/ /dev/shm/ # tmpfs /usr/bin/firefox --profile /dev/shm/firefox/c9999.default/
nor
cp -r ~/.mozilla/firefox/ /var/tmp # tmpfs /usr/bin/firefox --profile /var/tmp/c9999.default/
so. it is most likely fuse or overlayfs bug
without digging further, I'd say it is a kernel issue.
a FUSE program should not be able to cause that error, no matter how hard it tries.
Can you reproduce the issue? It is very simple steps.
