[PATCH 0/2] cpu: CPU hotplug lock updates

Posted by Reinette Chatre 4 days, 5 hours ago

resctrl would like to use lockdep_is_cpus_held() as the lockdep
expression provided to list_for_each_entry_rcu() but Sashiko pointed out
that lockdep_is_cpus_held() is undefined when CONFIG_HOTPLUG_CPU is unset.

Patch 2 adds stubs for lockdep_is_cpus_held() and lockdep_is_cpus_write_held().

Patch 1 supports this work by adding include/linux/cpuhplock.h to the
MAINTAINERS CPU HOTPLUG area to help ensure patches touching it are routed
correctly.

Applies against tip/master.

Reinette Chatre (2):
  MAINTAINERS: Add include/linux/cpuhplock.h to CPU HOTPLUG area
  cpu: Add lockdep_is_cpus_held()/lockdep_is_cpus_write_held() stubs for
    !CONFIG_HOTPLUG_CPU
