We currently don't lock the extent when we're doing a cow_file_range_inline() for a compressed extent. This isn't a problem necessarily, but it's inconsistent with the rest of our usage of cow_file_range_inline(). This also leads to some extra weird logic around whether the extent is locked or not. Fix this to lock the extent before calling cow_file_range_inline() in compression to make it consistent with the rest of the inline users. In future patches this will be pushed down into the cow_file_range_inline() helper, so we're fine with the quick and dirty locking here. This patch exists to make the behavior change obvious.

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 reStructuredText 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.
