Currently a kvfree_call_rcu() takes an offset within a structure as a second parameter, so a helper such as a kvfree_rcu_arg_2() has to convert rcu_head and a freed ptr to an offset in order to pass it. That leads to an extra conversion on macro entry. Instead of converting, refactor the code in way that a pointer that has to be freed is passed directly to the kvfree_call_rcu(). This patch does not make any functional change and is transparent to all kvfree_rcu() users. Signed-off-by: Uladzislau Rezki (Sony) <urezki@gmail.com> Signed-off-by: Paul E.

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.
