Drop kmem_alloc event class, and define kmalloc and kmem_cache_alloc
using TRACE_EVENT() macro.
And then this patch does:
- Do not pass pointer to struct kmem_cache to trace_kmalloc.
gfp flag is enough to know if it's accounted or not.
- Avoid dereferencing s->object_size and s->size when not using kmem_cache_alloc event.
- Avoid dereferencing s->name in when not using kmem_cache_free event.
- Adjust s->size to SLOB_UNITS(s->size) * SLOB_UNIT in SLOB

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.
