SUNRPC reverting d03727b248
("NFSv4 fix CLOSE not waiting for direct IO compeletion")
commit5.4-rM2-2.2.x-imx-squashed65caafd0d2
upstream. 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.
