Subject: [PATCH 0/9] watchdog: internally split softlockup and hardlockup
Date: Thu,  5 Feb 2015 15:40:16 -0500	[thread overview]
Message-ID: <1423168825-156238-1-git-send-email-dzickus@redhat.com> (raw)

The hardlockup and softockup had always been tied together.  Due to the request
of KVM folks, they had a need to have one enabled but not the other.
Internally rework the code to split things apart more cleanly.

There is a bunch of churn here, but the end result should be code that should
be easier to maintain and fix without knowing the internals of what is going
on.

Tested by Uli and myself.

Ulrich Obergfell (9):
  watchdog: new definitions and variables, initialization
  watchdog: introduce the proc_watchdog_update() function
  watchdog: move definition of 'watchdog_proc_mutex' outside of
    proc_dowatchdog()
  watchdog: introduce the proc_watchdog_common() function
  watchdog: introduce separate handlers for parameters in
    /proc/sys/kernel
  watchdog: implement error handling for failure to set up hardware
    perf events
  watchdog: enable the new user interface of the watchdog mechanism
  watchdog: clean up some function names and arguments
  watchdog: introduce the hardlockup_detector_disable() function
