The patch titled
Subject: watchdog: introduce separate handlers for parameters in /proc/sys/kernel
has been removed from the -mm tree. Its filename was
watchdog-introduce-separate-handlers-for-parameters-in-proc-sys-kernel.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Ulrich Obergfell <uobergfe@xxxxxxxxxx>
Subject: watchdog: introduce separate handlers for parameters in /proc/sys/kernel
Separate handlers for each watchdog parameter in /proc/sys/kernel replace
the proc_dowatchdog() function. Three of those handlers merely call
proc_watchdog_common() with one different argument.
