Subject: [RFC v1 0/6] block: add error handling for *add_disk*()

While working on some blktrace races I noticed that we don't do
error handling on *add_disk*() and friends. This is my initial
work on that.

This is based on linux-next tag next-20200428, you can also get this
on my branch 20200428-block-fixes [0].

Let me know what you think.

Luis Chamberlain (6):
  block: refcount the request_queue early in __device_add_disk()
  block: move disk announce work from register_disk() to a helper
  block: move disk invalidation from del_gendisk() into a helper
  block: move disk unregistration work from del_gendisk() to a helper
  block: add initial error handling for *add_disk()* and friends
  loop: add error handling support for add_disk()
