[LTP] [RFC PATCH 2/2] io: Remove stress_cd

Petr Vorel pvorel@suse.cz
Mon Jun 7 13:10:16 CEST 2021


Similarly to previous commit, also CDROM / DVD aren't much used
nowadays and thus it does not make much sense to keep and further
cleanup stress_cd.c.

Remove also diskio.sh, which was used only for stress_{cd,floppy}.
