Subject: [PATCH v1 0/1] usb: gadget: dummy_hcd: Fix regression due to hrtimer migration
Date: Wed, 26 Jun 2024 15:47:19 +0200 [thread overview]
Message-ID: <cover.1719405791.git.marcello.bauer@9elements.com> (raw)
The kernel CI bots such as syzbot and intel kernel bot reported a
regression due to the migration of the transfare scheduler from timer
list to hrtimer. The current assumption is that this is because timer
list uses soft interrupt context. I have not been able to reproduce the
regression consistently. So I'm submitting this patch in the hope that
it solves the issue.
Do not apply the patch if any bot still reports the problem.
