Miklos Szeredi c828e913c8 fuse: ioctl: translate ENOSYS in outarg ... commit 6a567e920f upstream. Fuse shouldn't return ENOSYS from its ioctl implementation. If userspace responds with ENOSYS it should be translated to ENOTTY. There are two ways to return an error from the IOCTL request: - fuse_out_header.error - fuse_ioctl_out.result Commit 02c0cab8e7 ("fuse: ioctl: translate ENOSYS") already fixed this issue for the first case, but missed the second case. This patch fixes the second case.
