As mentioned earlier, the repair strategy for file-based metadata is to build a new copy in a temporary file and swap the file fork mappings with the metadata inode. We've built the atomic extent swap facility, so now we need to build a facility for handling private temporary files. The first step is to teach the filesystem to ignore the temporary files. We'll mark them as PRIVATE in the VFS so that the kernel security modules will leave it alone. The second step is to add the online repair code the ability to create a temporary file and reap extents from the temporary file after the extent swap. This has been running on the djcloud for months with no problems. Enjoy! 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 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.
