In bond_reset_slave_arr(), values are assigned and memory is released only when the variables "usable" and "all" are not NULL. But even if the "usable" and "all" variables are NULL, they can still work, because value will be checked in kfree_rcu. Therefore, use bond_set_slave_arr() and set the input parameters "usable_slaves" and "all_slaves" to NULL to simplify the code in bond_reset_slave_arr(). And the same to bond_uninit().

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.
