Filipe Manana 20af93d97f btrfs: update stale comment for nowait direct IO writes 
If when doing a direct IO write we need to fallback to buffered IO, we
this comment at btrfs_direct_write() that says we can't directly fallback
to buffered IO if we have a NOWAIT iocb, because we have no support for
NOWAIT buffered writes. That is not true anymore, as support for NOWAIT
buffered writes was added recently in commit 926078b21d ("btrfs: enable
nowait async buffered writes").

However we still can't fallback to a buffered write in case we have a
NOWAIT iocb, because we'll need to flush delalloc and wait for it to
complete after doing the buffered write, and that can block for several
reasons, the main reason being waiting for IO to complete.

So update the comment to mention all that.

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.
