Convert the xfs_ialloc_has_inodes_at_extent function to return keyfill scan results because for a given range of inode numbers, we might have no indexed inodes at all; the entire region might be allocated ondisk inodes; or there might be a mix of the two. Unfortunately, sparse inodes adds to the complexity, because each inode record can have holes, which means that we cannot use the generic btree _scan_keyfill function because we must look for holes in individual records to decide the result. On the plus side, online fsck can now detect sub-chunk discrepancies in the inobt. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Dave Chinner <dchinner@redhat.com>
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.
