Currently we calculate inline extent read in a way that inline extent can start at non-zero offset. This is consistent with the inode selftests, which puts an inline extent at file offset 5. Meanwhile the inline extent creation code will only create inline extent at file offset 0. Furthermore with the introduction of tree-checker on file extents, we are actively rejecting inline extent which starts at non-zero file offset. And so far we haven't yet seen any report of rejected inline extents at non-zero file offset. This all means, the extra calculation to support inline extents at non-zero file offset is mostly paper weight, and damaging the readability of the code. Thus this patch will: - Add extra ASSERT()s to make sure involved file offset are all 0 - Remove @extent_offset calculation - Simplify the involved code As several variables are now single-use, no need to declare them as a variable anymore.

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.
