In preparation for supporting repair of indexed file-based metadata (such as realtime bitmaps, directories, and extended attribute data), add a function to reap the old blocks after a metadata repair finishes. IOWs, this is an elaborate bunmapi call that deals with crosslinked blocks by unmapping them without freeing them, and also scans for incore buffers to invalidate. 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.
