Severity: normal

Hi,
valgrind outputs a spurious warning on
ioctl(fd,VT_GETSTATE,&vt_stat);
==19992== Syscall param ioctl(VT_GETSTATE) points to uninitialised byte(s)
==19992== at 0x500AAB7: ioctl (in /lib/libc-2.5.so)
The vt_stat structure is not read by the kernel, and hence doesn't need
to be initialized. The attached patch fixes that.
