ext4_fallocate() is only used in the file_operations for regular files. Also, the VFS only allows fallocate() on regular files and block devices, but block devices always use blkdev_fallocate(). For both of these reasons, S_ISREG() is always true in ext4_fallocate(). Therefore the S_ISREG() checks in ext4_zero_range(), ext4_collapse_range(), ext4_insert_range(), and ext4_punch_hole() are redundant. Remove them.

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.
