87bb5b6001Simplify the control flow of mount_setattr_{prepare,commit} so they
become easier to follow. We kept using both an integer error variable
that was passed by pointer as well as a pointer as an indicator for
whether or not we need to revert or commit the prepared changes.
Simplify this and just use the pointer. If we successfully changed
properties the revert pointer will be NULL and if we failed to change
properties it will indicate where we failed and thus need to stop
reverting.

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.
