But cdrom_read_toc is the routine that called this in
the first place. That would create an infinite loop. Here, again,
is the call graph from my original email:
Routine File
cdrom_read_toc ide/ide-cd.c
cdrom_get_last_written cdrom/cdrom.c
ide_cdrom_audio_ioctl ide/ide-cd.c
cdrom_get_toc_entry ide/ide-cd.c
