bc44fa73 - watchdog: make nowayout sysfs file writable

Tue, 05 Nov 2019 20:51:18 +0000

watchdog: make nowayout sysfs file writableIt can be useful to delay setting the nowayout feature for a watchdogdevice. Moreover, not every driver (notably gpio_wdt) implements anowayout module parameter/otherwise respects CONFIG_WATCHDOG_NOWAYOUT,and modifying those drivers carries a risk of causing a regression forsomeone who has two watchdog devices, sets CONFIG_WATCHDOG_NOWAYOUTand somehow relies on the gpio_wdt driver being ignorant ofthat (i.e., allowing one to gracefully close a gpio_wdt but not theother watchdog in the system).So instead, simply make the nowayout sysfs file writable. Obviously,setting nowayout is a one-way street.Signed-off-by: Rasmus Villemoes Reviewed-by: Guenter Roeck Link: https://lore.kernel.org/r/20191105205118.11359-1-linux@rasmusvillemoes.dkSigned-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck List of files: /linux-6.15/Documentation/ABI/testing/sysfs-class-watchdog
