| H A D | nfs4file.c | 5ee3d10f Thu Jun 09 19:46:29 CDT 2022 Dave Wysochanski <dwysocha@redhat.com> NFSv4: Add FMODE_CAN_ODIRECT after successful open of a NFS4.x file
Commit a2ad63daa88b ("VFS: add FMODE_CAN_ODIRECT file flag")
added the FMODE_CAN_ODIRECT flag for NFSv3 but neglected to add
it for NFSv4.x. This causes direct io on NFSv4.x to fail open
with EINVAL:
mount -o vers=4.2 127.0.0.1:/export /mnt/nfs4
dd if=/dev/zero of=/mnt/nfs4/file.bin bs=128k count=1 oflag=direct
dd: failed to open '/mnt/nfs4/file.bin': Invalid argument
dd of=/dev/null if=/mnt/nfs4/file.bin bs=128k count=1 iflag=direct
dd: failed to open '/mnt/dir1/file1.bin': Invalid argument
Fixes: a2ad63daa88b ("VFS: add FMODE_CAN_ODIRECT file flag")
