Joanne Koong 595d7ebeaf fuse: remove page alignment check for writeback len
Remove incorrect page alignment check for the writeback len arg in
fuse_iomap_writeback_range().  len will always be block-aligned as
passed in by iomap.

On regular fuse filesystems, i_blkbits is set to PAGE_SHIFT so this is
not a problem but for fuseblk filesystems, the block size is set to a
default of 512 bytes or a block size passed in at mount time.

Please note that non-page-aligned lengths are fine for the logic in
fuse_iomap_writeback_range().  The check was originally added as a
safeguard to detect conspicuously wrong ranges.

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.
