No, it didn't make any difference. I added a printk to do_getname()
and I see that it is called with filename==0.
I disabled the framebuffer so I could boot the kernel, then wrote a
small test program that does open(0, O_RDONLY). This also calls
do_getname() with filename==0, but does not generate an oops. Maybe
there is something wrong with exception handling that early in the
boot sequence.
