[ Upstream commit 9ce3c0d26c42d279b6c378a03cd6a61d828f19ca ] Testcase: 1. create a minix file system and mount it 2. open a file on the file system with O_RDWR|O_CREAT|O_TRUNC|O_DIRECT 3. open fails with -EINVAL but leaves an empty file behind. All other open() failures don't leave the failed open files behind. It is hard to check the direct_IO op before creating the inode. Just as ext4 and btrfs do, this patch will resolve the issue by allowing to create the file with O_DIRECT but returning error when writing the file.

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.
