(Take a look at attachment.) At least the kernel does not panic. ;) Thanks, -- Mateusz Guzik ------=_Part_20104_30199813.1218014656704 Content-Type: application/octet-stream; name=vfs_mount.diff Content-Transfer-Encoding: base64 X-Attachment-Id: f_fjjqf5in0 Content-Disposition: attachment; filename=vfs_mount.diff LS0tIHN5cy9rZXJuL3Zmc19tb3VudC5jLm9yaWcJMjAwOC0wOC0wNiAxMToxNDoxNi4wMDAwMDAw MDAgKzAyMDAKKysrIHN5cy9rZXJuL3Zmc19tb3VudC5jCTIwMDgtMDgtMDYgMTE6MTQ6MzIuMDAw MDAwMDAwICswMjAwCkBAIC0xOTYsMTAgKzE5NiwxMyBAQAogdm9pZAogdmZzX2RlbGV0ZW9wdChz dHJ1Y3QgdmZzb3B0bGlzdCAqb3B0cywgY29uc3QgY2hhciAqbmFtZSkKIHsKIAlzdHJ1Y3QgdmZz b3B0ICpvcHQsICp0ZW1wOwogCisJaWYgKG9wdHMgPT0gTlVMTCkKKwkJcmV0dXJuOworCiAJVEFJ TFFfRk9SRUFDSF9TQUZFKG9wdCwgb3B0cywgbGluaywgdGVtcCkgIHsKIAkJaWYgKHN0cmNtcChv cHQtPm5hbWUsIG5hbWUpID09IDApCiAJCQl2ZnNfZnJlZW9wdChvcHRzLCBvcHQpOwogCX0KIH0K ------=_Part_20104_30199813.1218014656704--
