Subject: [PATCH 4.4 132/137] 6pack,mkiss: fix possible deadlock
Date: Thu,  2 Jan 2020 23:08:25 +0100	[thread overview]
Message-ID: <20200102220604.949290907@linuxfoundation.org> (raw)
In-Reply-To: <20200102220546.618583146@linuxfoundation.org>

From: Eric Dumazet <edumazet@google.com>

commit 5c9934b6767b16ba60be22ec3cbd4379ad64170d upstream.

We got another syzbot report [1] that tells us we must use
write_lock_irq()/write_unlock_irq() to avoid possible deadlock.
