When we update a directory, a number of errors may happen. If we failed to find the entry to update, we can just release the directory buffers as normal. However, if we have some other error, we may have partially updated the buffers, resulting in an invalid directory. In this case, we need to discard the buffers to avoid writing the contents back to the media, and later re-read the directory from the media.

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.
