Currently, the kfree() be used for pwq objects allocated with kmem_cache_alloc() in alloc_and_link_pwqs(), this isn't wrong. but usually, use "trace_kmem_cache_alloc/trace_kmem_cache_free" to track memory allocation and free. this commit therefore use kmem_cache_free() instead of kfree() in alloc_and_link_pwqs() and also consistent with release of the pwq in rcu_free_pwq().

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.
