Michal Hocko 847f716f9e net/ipv6/ila/ila_xlat.c: simplify a strange allocation pattern
alloc_ila_locks seemed to c&p from alloc_bucket_locks allocation pattern
which is quite unusual.  The default allocation size is 320 *
sizeof(spinlock_t) which is sub page unless lockdep is enabled when the
performance benefit is really questionable and not worth the subtle code
IMHO.  Also note that the context when we call ila_init_net (modprobe or
a task creating a net namespace) has to be properly configured.

Let's just simplify the code and use kvmalloc helper which is a
transparent way to use kmalloc with vmalloc fallback.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
