Subject: [PATCH 2/5] ACPI: Create symlinks in acpi_bind_one() under physical_node_lock
Date: Tue, 06 Aug 2013 02:26:46 +0200 [thread overview]
Message-ID: <5865465.O2TCJ2dK9V@vostro.rjw.lan> (raw)
In-Reply-To: <3015032.qfOqgEVZKP@vostro.rjw.lan>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Put the creation of symlinks in acpi_bind_one() under the
physical_node_lock mutex of the given ACPI device objects, because
that is part of the binding operation logically (those links are
already removed under that mutex too).
