Hello Jens,
The two patches in this series fix a race condition related to the creation of
the sysfs attributes for the /dev/nvme0n<x> devices nodes. I encountered this
race while adding tests to the blktests project for the NVMeOF kernel
drivers. Please consider these patches for the upstream kernel.
Thanks,
Bart.

I have fixed the very same thing with my patchset titled "genhd:
register default groups with device_add_disk" which is waiting for
inclusion.
Cheers,
Hannes
