kref release routines usually perform memory release operations,
hence, they should not be called with spinlocks held.
one such case is: SIW kref release routine siw_free_qp(), which
can sleep via vfree() while freeing queue memory.
Hence, all iw_rem_ref() calls in IWCM are moved out of spinlocks.

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.
