Replace the open-coded checks for whether or not an inode fork maps blocks with a macro that will implant the code for us. This helps us declutter the bmap code a bit. Note that I had to use a macro instead of a static inline function because of C header dependency problems between xfs_inode.h and xfs_inode_fork.h. Conversion was performed with the following Coccinelle script: @@ expression ip, w; @@ - XFS_IFORK_FORMAT(ip, w) == XFS_DINODE_FMT_EXTENTS || XFS_IFORK_FORMAT(ip, w) == XFS_DINODE_FMT_BTREE + xfs_ifork_has_extents(ip, w) @@ expression ip, w; @@ - XFS_IFORK_FORMAT(ip, w) != XFS_DINODE_FMT_EXTENTS && XFS_IFORK_FORMAT(ip, w) != XFS_DINODE_FMT_BTREE + !xfs_ifork_has_extents(ip, w) @@ expression ip, w; @@ - XFS_IFORK_FORMAT(ip, w) == XFS_DINODE_FMT_BTREE || XFS_IFORK_FORMAT(ip, w) == XFS_DINODE_FMT_EXTENTS + xfs_ifork_has_extents(ip, w) @@ expression ip, w; @@ - XFS_IFORK_FORMAT(ip, w) != XFS_DINODE_FMT_BTREE && XFS_IFORK_FORMAT(ip, w) != XFS_DINODE_FMT_EXTENTS + !xfs_ifork_has_extents(ip, w) @@ expression ip, w; @@ - (xfs_ifork_has_extents(ip, w)) + xfs_ifork_has_extents(ip, w) @@ expression ip, w; @@ - (!xfs_ifork_has_extents(ip, w)) + !xfs_ifork_has_extents(ip, w) 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 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.
