9P optionally uses the FS_IOC_GETVERSION ioctl to get information about a file's version (sometimes called generation number). The code checks for supported filesystems at mount time, but some paths may come from other mounted filesystems. Change it to treat unsupported paths the same as unsupported filesystems, returning 0 in both cases. Note: ENOTTY is the error code for an unsupported ioctl. This fix allows booting a linux kernel with the same / filesystem as the host; otherwise the boot fails when mounting devtmpfs.
