There are several reasons to add a general function ext4_mb_mark_context to update block bitmap and group descriptor on disk: 1. pair behavior of alloc/free bits. For example, ext4_mb_new_blocks_simple will update free_clusters in struct flex_groups in ext4_mb_mark_bb while ext4_free_blocks_simple forgets this. 2. remove repeat code to read from disk, update and write back to disk. 3. reduce future unit test mocks to catch real IO to update structure on disk.

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.
