This is a note to let you know that I've just added the patch titled nvme-pci: add the IGNORE_DEV_SUBNQN quirk for Intel P4500/P4600 SSDs to the 5.16-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: nvme-pci-add-the-ignore_dev_subnqn-quirk-for-intel-p.patch and it can be found in the queue-5.16 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 66d2c36a67f0e5943a875712324e15a8aec6f809 Author: Wu Zheng <wu.zheng@xxxxxxxxx> Date: Mon Jun 21 19:07:01 2021 -0400 nvme-pci: add the IGNORE_DEV_SUBNQN quirk for Intel P4500/P4600 SSDs [ Upstream commit 25e58af4be412d59e056da65cc1cefbd89185bd2 ] The Intel P4500/P4600 SSDs do not report a subsystem NQN despite claiming compliance to a standards version where reporting one is required. Add the IGNORE_DEV_SUBNQN quirk to not fail the initialization of a second such SSDs in a system.
