Subject: watchdog/hardlockup: in watchdog_hardlockup_check() use cpumask_copy()
Date: Fri, 26 May 2023 18:41:34 -0700
In the patch ("watchdog/hardlockup: add a "cpu" param to
watchdog_hardlockup_check()") we started using a cpumask to keep track of
which CPUs to backtrace. When setting up this cpumask, it's better to use
cpumask_copy() than to just copy the structure directly. Fix this.
