Subject: [PATCH 05/27] HID: wacom: use one work queue per task
Date: Tue, 5 Jul 2016 16:39:01 +0200 [thread overview]
Message-ID: <1467729563-23318-6-git-send-email-benjamin.tissoires@redhat.com> (raw)
In-Reply-To: <1467729563-23318-1-git-send-email-benjamin.tissoires@redhat.com>
Looks like the battery hijacked the wireless worker. That's not fair so
use a work queue per task.
