Subject: [PATCH v1 1/8] docs: watchdog: codify ident.options as superset of possible status flags
Date: Thu, 11 Jun 2020 21:17:42 +0200
Message-ID: <20200611191750.28096-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200611191750.28096-1-a.fatoum@pengutronix.de>

The FIXME comment has been in-tree since the very first git commit.
The described behavior has been since relied on by some userspace, e.g.
the util-linux wdctl command and has been ignored by some kernelspace,
like the f71808e_wdt driver.

The functionality is useful to have to be able to differentiate between a
driver that doesn't support WDIOF_CARDRESET and one that does, but hasn't
had a watchdog reset, thus drop the FIXME to encourage drivers adopting
this convention.
