AW: [PATCH] nvme-pci: mark Seagate Nytro XM1440 as QUIRK_NO_NS_DESC_LIST.

[Julian Einwag]

Christoph,

I'm sorry - I already sent a re-formatted patch with the added sign-off, but it looks like the message didn't go through. So here it is, again:

---
The kernel fails to fully detect these SSDs, only the character devices
are present:

[   10.785605] nvme nvme0: pci function 0000:04:00.0
[   10.876787] nvme nvme1: pci function 0000:81:00.0
[   13.198614] nvme nvme0: missing or invalid SUBNQN field.
[   13.198658] nvme nvme1: missing or invalid SUBNQN field.
[   13.206896] nvme nvme0: Shutdown timeout set to 20 seconds
[   13.215035] nvme nvme1: Shutdown timeout set to 20 seconds
[   13.225407] nvme nvme0: 16/0/0 default/read/poll queues
[   13.233602] nvme nvme1: 16/0/0 default/read/poll queues
[   13.239627] nvme nvme0: Identify Descriptors failed (8194)
[   13.246315] nvme nvme1: Identify Descriptors failed (8194)

Adding the NVME_QUIRK_NO_NS_DESC_LIST fixes this problem.
