Qinghua Jin 94d236c863 minix: fix bug when opening a file with O_DIRECT ... [ Upstream commit 9ce3c0d26c ] 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.
