Subject: [GIT PULL] Block fixes for 4.6-rc

Hi Linus,

A few fixes for the current series. This pull request contains:

- Two fixes for NVMe. One fixes a reset race that can be triggered by
  repeated insert/removal of the module. The other fixes an issue on
  some platforms, where we get probe timeouts since legacy interrupts
  isn't working. This used not to be a problem since we had the worker
  thread poll for completions, but since that was killed off, it means
  those poor souls can't successfully probe their NVMe device. Use a
  proper IRQ check and probe (msi-x -> msi ->legacy), like most other
  drivers to work around this. Both from Keith.

- A loop corruption issue with offset in iters, from Ming Lei.

- A fix for not having the partition stat per cpu ref count initialized
  before sending out the KOBJ_ADD, which could cause user space to
  access the counter prior to initialization. Also from Ming Lei.

- A fix for using the wrong congestion state, from Kaixu Xia.

Please pull!
