commit65caafd0d2upstream. Reverting commitd03727b248"NFSv4 fix CLOSE not waiting for direct IO compeletion". This patch made it so that fput() by calling inode_dio_done() in nfs_file_release() would wait uninterruptably for any outstanding directIO to the file (but that wait on IO should be killable). The problem the patch was also trying to address was REMOVE returning ERR_ACCESS because the file is still opened, is supposed to be resolved by server returning ERR_FILE_OPEN and not ERR_ACCESS.

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.
