[PATCH 0/2] nvmet: fix subtle race in I/O processing and ns configuration

[Nilay Shroff <nilay@linux.ibm.com>]

Hi,

This series addresses two race conditions in the nvmet core code that
handles I/O submission and namespace configuration.

The first patch addresses a race where target namespace attributes
could be changed while I/O is in progress. The second patch addresses
a subtle race that could allow I/O to be admitted even after the
percpu reference count has been killed or marked dead.

As usual, feedback, comments, and suggestions are most welcome!

Thanks!

  nvmet: defer setting ns->enabled to false in nvmet_ns_disable()
  nvmet: don't allow I/O admission after percpu ns reference is killed
