84d56e66b9b4a646f04ec30696ca1aeea5e654d5 is the first bad commit commit 84d56e66b9b4a646f04ec30696ca1aeea5e654d5 Author: Ulrich Obergfell <uobergfe@redhat.com> AuthorDate: Tue Apr 14 15:43:55 2015 -0700 Commit: Linus Torvalds <torvalds@linux-foundation.org> CommitDate: Tue Apr 14 16:48:58 2015 -0700 watchdog: new definitions and variables, initialization 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. This patch (of 9): Introduce new definitions and variables to separate the user interface in /proc/sys/kernel from the internal run state of the lockup detectors. The internal run state is represented by two bits in a new variable that is named 'watchdog_enabled'. This helps simplify the code, for example: - In order to check if any of the two lockup detectors is enabled, it is sufficient to check if 'watchdog_enabled' is not zero. - In order to enable/disable one or both lockup detectors, it is sufficient to set/clear one or both bits in 'watchdog_enabled'. - Concurrent updates of 'watchdog_enabled' need not be synchronized via a spinlock or a mutex. Updates can either be atomic or concurrency can be detected by using 'cmpxchg'.
