There are 3 places where those counters (many and varied...) are adjusted - when we are freeing fragments and get an entire block freed, when we are freeing blocks and (in opposite direction) when we are grabbing a block. The logics is identical (modulo the sign of adjustment) in all three; better take it into a helper - less duplication and less clutter in the callers that way.

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.
