Slab caches marked with SLAB_ACCOUNT force accounting for every allocation from this cache even if __GFP_ACCOUNT flag is not passed. Unfortunately, at the moment this flag is not visible in ftrace output, and this makes it difficult to analyze the accounted allocations. This patch adds boolean "accounted" entry into trace output, and set it to 'true' for calls used __GFP_ACCOUNT flag and for allocations from caches marked with SLAB_ACCOUNT. Set it to 'false' if accounting is disabled in configs.

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.
