	Subject: kernel-source-2.4.18: kernel ignores noexec and mode option in cdrom case
	Message-ID: <20020924162129.A328@pisidlo>

In /etc/fstab i have following line:
/dev/cdrom      /cdrom          iso9660  gid=100,noauto,ro,noexec,mode=0444,user      0       0

I found on one CD that some files have exec bit set. From brief view
those files has no extension (filename.ext).

My drive is asus-1610a (ATAPI writer) connected throught scsi-emulation.
