In production, show_mem() can be called concurrently from two different entities, for example one from oom_kill_process() another from __alloc_pages_slowpath from another kthread. This patch adds a spinlock and invokes trylock before printing out the kernel alloc info in show_mem(). This way two alloc info won't interleave with each other, which then makes parsing easier.

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 reStructuredText 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.
