Linux kernel source tree

Now target is removed from nvme_fc_ctrl_free() which is the ctrl->ref release handler. And even admin queue is unquiesced there, this way is definitely wrong because the ctr->ref is grabbed when submitting command. And Marco observed that nvme_fc_ctrl_free() can be called from request completion code path, and trigger kernel warning since request completes from softirq context. Fix the issue by moveing target removal into nvme_fc_delete_ctrl(), which is also aligned with nvme-tcp and nvme-rdma. Patch originally proposed by Ming Lei, then modified to move the tagset removal down to after nvme_fc_delete_association() after further testing.

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 reStructuredText 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.
