There is a comment at btrfs_replace_file_extents() that mentions that we
set the full sync flag on an inode when cloning into a file with a size
greater than or equals to 16MiB, through try_release_extent_mapping() when
we truncate the page cache after replacing file extents during a clone
operation.
That is not true anymore since commit 5e548b32018d96 ("btrfs: do not set
the full sync flag on the inode during page release"), so update the
comment to remove that part and rephrase it slightly to make it more
clear why the full sync flag is set at btrfs_replace_file_extents().

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.
