Track number of allocations where the length of blocks allocated is equal to the length of goal blocks (post normalization). This metric could be useful if making changes to the allocator logic in the future as it could give us visibility into how often do we trim our requests. PS: ac_b_ex.fe_len might get modified due to preallocation efforts and hence we use ac_f_ex.fe_len instead since we want to compare how much the allocator was able to actually find.

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.
