Earlier, in commit 1dd214b8f2 ("mm: page_alloc: avoid merging
non-fallbackable pageblocks with others"), migrate type MIGRATE_CMA and
MIGRATE_ISOLATE are removed from fallbacks list since they are never used.
Later on, in commit ("aa02d3c174ab mm/page_alloc: reduce fallbacks to
(MIGRATE_PCPTYPES - 1)"), the array column size is reduced to
'MIGRATE_PCPTYPES - 1'. In fact, the array row size need be reduced to
MIGRATE_PCPTYPES too since it's only covering rows of the number
MIGRATE_PCPTYPES. Even though the current code has handled cases
when the migratetype is CMA, HIGHATOMIC and MEMORY_ISOLATION, making
the row size right is still good to avoid future error and confusion.

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.
