Upstream commit 4ab7ace465 ("lib/test_meminit.c: minor test fixes").
Fix the following issues in test_meminit.c:
- |size| in fill_with_garbage_skip() should be signed so that it
doesn't overflow if it's not aligned on sizeof(*p);
- fill_with_garbage_skip() should actually skip |skip| bytes;
- do_kmem_cache_size() should deallocate memory in the RCU case.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
