The purpose of this function is to unlock all nodes in a btrfs path which are above 'lowest_unlock' and whose slot used is different than 0. As such it used slightly awkward structure of 'if' as well as somewhat cryptic "no_skip" control variable which denotes whether we should check the current level of skipability or no. This patch does the following (cosmetic) refactorings: * Renames 'no_skip' to 'check_skip' and makes it a boolean. This variable controls whether we are below the lowest_unlock/skip_level levels. * Consolidates the 2 conditions which warrant checking whether the current level should be skipped under 1 common if (check_skip) branch, this increase indentation level but is not critical. * Consolidates the 'skip_level < i && i >= lowest_unlock' and 'i >= lowest_unlock && i > skip_level' condition into a common branch since those are identical. * Eliminates the local extent_buffer variable as in this case it doesn't bring anything to function readability.

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.
