Subject: [PATCH 5.10 110/126] USB: cdc-acm: untangle a circular dependency between callback and softint
Date: Mon, 5 Apr 2021 10:54:32 +0200 [thread overview]
Message-ID: <20210405085034.677222525@linuxfoundation.org> (raw)
In-Reply-To: <20210405085031.040238881@linuxfoundation.org>
From: Oliver Neukum <oneukum@suse.com>
commit 6069e3e927c8fb3a1947b07d1a561644ea960248 upstream.
We have a cycle of callbacks scheduling works which submit
URBs with thos callbacks. This needs to be blocked, stopped
and unblocked to untangle the circle.
The issue leads to faults like:
