Subject: [PATCH v2 05/30] HID: wacom: use one work queue per task
Date: Wed, 13 Jul 2016 18:05:52 +0200 [thread overview]
Message-ID: <1468425977-4819-6-git-send-email-benjamin.tissoires@redhat.com> (raw)
In-Reply-To: <1468425977-4819-1-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.
