We have a big chunk of code inside a while() loop, with tons of strange jumps for error handling. It's definitely not to the code standard of today. Move the code into a new function, submit_one_async_extent(). Since we're here, also do the following changes: - Comment style change To follow the current scheme - Don't fallback to non-compressed write then hitting ENOSPC If we hit ENOSPC for compressed write, how could we reserve more space for non-compressed write? Thus we go error path directly. This removes the retry: label. - Add more comment for super long parameter list Explain which parameter is for, so we don't need to check the prototype. - Move the error handling to submit_one_async_extent() Thus no strange code like: out_free: ... goto again; Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
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.
