The following changes are made to enable userspace to obtain 64-bit extent counters, 1. Carve out a new 64-bit field xfs_bulkstat->bs_extents64 from xfs_bulkstat->bs_pad[] to hold 64-bit extent counter. 2. Define the new flag XFS_BULK_IREQ_BULKSTAT for userspace to indicate that it is capable of receiving 64-bit extent counters. Reviewed-by: Dave Chinner <dchinner@redhat.com> Reviewed-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.
