-Subject: padata: always acquire cpu_hotplug_lock before pinst->lock
-
-From: Daniel Jordan <daniel.m.jordan@oracle.com>
-
-[ Upstream commit 38228e8848cd7dd86ccb90406af32de0cad24be3 ]
-
-lockdep complains when padata's paths to update cpumasks via CPU hotplug
-and sysfs are both taken:
-
- # echo 0 > /sys/devices/system/cpu/cpu1/online
- # echo ff > /sys/kernel/pcrypt/pencrypt/parallel_cpumask
-
- ======================================================
- WARNING: possible circular locking dependency detected
- 5.4.0-rc8-padata-cpuhp-v3+ #1 Not tainted
- ------------------------------------------------------
- bash/205 is trying to acquire lock:
- ffffffff8286bcd0 (cpu_hotplug_lock.rw_sem){++++}, at: padata_set_cpumask+0x2b/0x120
-
- but task is already holding lock:
- ffff8880001abfa0 (&pinst->lock){+.+.}, at: padata_set_cpumask+0x26/0x120
-
- which lock already depends on the new lock.
-
-padata doesn't take cpu_hotplug_lock and pinst->lock in a consistent
-order. Which should be first? CPU hotplug calls into padata with
-cpu_hotplug_lock already held, so it should have priority.
