[PATCH 00/15] Fix issue with KOBJ_ADD uevent versus disk attributes
...ers to device_add_disk, so it can
be added before KOBJ_ADD.
Also add basic error handling around device_add_disk code, (or add FIXME
comment where work is left).
Fam Zheng (15):
disk: Drop add_disk in favor of device_add_disk
genhd: Return error from register_disk()
genhd: Return error from blk_register_region
block: Return error from blk_integrity_add
genhd: Return error from disk_{add,alloc}_events
genhd: Add return code to device_add_disk
genhd: Add attribute group parameter to device_add_disk

[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
