Summary: The unix `patch` command attempts to issue an `FS_IOC_GETFLAGS` ioctl and blows up when we return `ENOSYS`. The man page for ioctl says: ``` ENOTTY The specified request does not apply to the kind of object that the file descriptor fd references. ``` so let's return that error code to ioctl. In addition, the integration test I added for this trips up when it calls `llistxattr` on the file; turns out we don't need to insert the `fuse_getxattr_out` when we're returning the attribute list and that it is only needed when measuring up the required length, so let's move things around to resolve this and make it clearer.
