Subject: [PATCH 275/290] cpu/rt: Fix cpu_hotplug variable initialization
|
|
|
|
The commit "cpu/rt: Rework cpu down for PREEMPT_RT" changed the double
|
|
meaning of the cpu_hotplug.lock, where it was a spinlock for RT and a
|
|
mutex for non-RT, to just a mutex for both. But the initialization of
|
|
the variable was not updated to reflect this change.
