This patch series attempts to finish resolving the feedback received
from Petr Mladek on the v5 series I posted. Andrew has already landed
v5 so I'm posting this as additional patches.
Probably the only thing that wasn't fully as clean as Petr requested
was the Kconfig stuff. I couldn't find a better way to express it
without a more major overhaul. In the very least, I renamed "NON_ARCH"
to "PERF_OR_BUDDY" in the hopes that will make it marginally better.
Nothing in this series is terribly critical and even the bugfixes are
small. However, it does cleanup a few things that were pointed out in
review.
Douglas Anderson (10):
watchdog/hardlockup: Keep kernel.nmi_watchdog sysctl as 0444 if probe
fails
watchdog/hardlockup: HAVE_NMI_WATCHDOG must implement
watchdog_hardlockup_probe()
watchdog/hardlockup: Don't use raw_cpu_ptr() in
watchdog_hardlockup_kick()
watchdog/hardlockup: In watchdog_hardlockup_check() use cpumask_copy()
watchdog/hardlockup: remove softlockup comment in touch_nmi_watchdog()
watchdog/buddy: Cleanup how watchdog_buddy_check_hardlockup() is
called
watchdog/buddy: Don't copy the cpumask in watchdog_next_cpu()
watchdog/buddy: Simplify the dependency for
