Make nvme_ns_remove match the assumptions elsewhere. 1) !NVME_NS_READY needs to be srcu synchronized to make sure nothing is running in __nvme_find_path or nvme_round_robin_path that will re-assign this ns to current_path. 2) Any matching current_path entries need to be cleared before removing from the siblings list, to prevent calling nvme_round_robin_path with an "old" ns that's off list. 3) Finally the list_del_rcu can happen, and then synchronize again before releasing any reference counts.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
