Currently ext4_mb_clear_bb() & ext4_group_add_blocks() only checks whether the given block ranges (which is to be freed) belongs to any FS metadata blocks or not, of the block's respective block group. But to detect any FS error early, it is better to add more strict checkings in those functions which checks whether the given blocks belongs to any critical FS metadata or not within system-zone.

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.
