Now that the eofblocks code has been removed, we don't need to assign 0 to err before calling ext4_ext_insert_extent() since it will assign a return value to ret anyway. The variable free_on_err can be eliminated and replaced by a reference to allocated_clusters which clearly conveys the idea that newly allocated blocks should be freed when recovering from an extent insertion failure. The error handling code itself should be restructured so that it errors out immediately on an insertion failure in the case where no new blocks have been allocated (bigalloc) rather than proceeding further into the mapping code. The initializer for fb_flags can also be rearranged for improved readability. Finally, insert a missing space in nearby code. No known bugs are addressed by this patch - it's simply a cleanup.

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.
