Jan Kara pointed out that the VFS doesn't take i_rwsem of a child subdirectory that is being moved from one parent to another. Upon deeper analysis, I realized that this was the source of a very hard to trigger false corruption report in the parent pointer checking code. Now that we've refactored how directory walks work in scrub, we can also get rid of all the unnecessary and broken locking to make parent pointer scrubbing work properly. Signed-off-by: Darrick J.

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.
