We (or rather Dan) is touching most add_disk callers anyway for the
driverfs_dev removal. Let's just pass the array of attributes to
a disk_add variant and solve the issue for real.

I thought about that. Its usage is more compact compared to this series, but is
also more code and less flexible IMO. For example, we need at least two

virtio-pci acquires its spin lock in an interrupt context so it's necessary
to use spin_lock_irqsave/restore variants. This patch fixes guest SMP when

[PATCH v2 00/12] gendisk: Generate uevent after attribute available
The race condition is noticed between disk_add() and disk attributes, on
virtio-blk hotplug.
Userspace listens to the KOBJ_ADD uevent generated in add_disk(). At that
point we haven't created the serial attribute file, therefore depending
on how fast udev reacts, the /dev/disk/by-id/ entry doesn't always get
created.
As pointed out by Christoph Hellwig in the specific fix [1], virtio-blk
