We can just check f2fs_lfs_mode() directly. The block_unaligned_IO() check is redundant because in LFS mode, f2fs doesn't do direct I/O writes that aren't block-aligned (due to f2fs_force_buffered_io() returning true in this case, triggering the fallback to buffered I/O).

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.
