Subject: [PATCH] Fix watchdog drivers to call emergency_reboot()
X-Git-Tag: Ubuntu-5.13.0-19.19~64552
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=f82567e55fcd25bb7addf2cfd8b79f36f409dc2e;p=mirror_ubuntu-jammy-kernel.git

[PATCH] Fix watchdog drivers to call emergency_reboot()

If a watchdog driver has decided it is time to reboot the system
we know something is wrong and we are in interrupt context
so emergency_reboot() is what we want.
