[PATCH 0/2] watchdog: Provide user control over WDOG_STOP_ON_REBOOT

From: Dmitry Safonov
Date: Thu Feb 13 2020 - 13:00:08 EST


Add WDIOS_RUN_ON_REBOOT and WDIOS_STOP_ON_REBOOT to control the
watchdog's behavior over reboot.

Changes since RFC:
o rebase over v5.6
o fixed return code for ioctl()

I've sent RFC a while ago and it probably was very late in release
cycle to catch any attention:
https://lkml.kernel.org/r/20200121162145.166334-1-dima@xxxxxxxxxx

While waiting for rc1, I've changed my mind that it's RFC material and
sending it as PATCHv1 instead.
