Hi,
I’m using some CIFS mounts and in past days I’ve faced following issue :
some applications cannot be killed , I cannot do a sudo , I cannot launch some Flatpak applications and I cannot shutdown my computer properly.
It seems to be related to a kernel 6.13 bug (netfs: Can’t donate prior to front). Today it happened just using vlc playing a movie on my NAS. So beware.
Detailed trace :

Seems there was a similar issue for 6.13.1 : https://lore.kernel.org/all/CAKPOu+_4mUwYgQtRTbXCmi±k3PGvLysnPadkmHOyB7Gz0iSMA@mail.gmail.com/T/
I’m using kernel 6.13.9-200.fc41.x86_64 . Will try to see if 6.13.10-200.fc41.x86_64 fixes it..
