Subject: Re: [PATCH] PCI/hotplug: Replaced down_write_nested with hotplug_slot_rwsem if ctrl->depth > 0 when taking the ctrl->reset_lock.
Date: Mon, 23 Jan 2023 14:30:03 -0500	[thread overview]
Message-ID: <22a64441-5eed-8d56-5c5e-80c425cf6967@amd.com> (raw)
In-Reply-To: <20230121072148.GA13969@wunner.de>

I do not see a deadlock, when applying the following old patch:
https://lore.kernel.org/linux-pci/908047f7699d9de9ec2efd6b79aa752d73dab4b6.1595329748.git.lukas@wunner.de/
after merge for the kernel 6.2.0-rc5, and applied the alternative patch:
https://patchwork.kernel.org/project/linux-pci/patch/3dc88ea82bdc0e37d9000e413d5ebce481cbd629.1674205689.git.lukas@wunner.de/

I have uploaded the merged patch and the system log for the upstream kernel.

Anatoli
