mount: "mount -o rw ...." should not fall back to RO mount
The reported case was an attempt to remount,rw a CD-ROM:
mount -o remount,rw /mnt/sr0
which "succeeded" by falling back to RO:
mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = -1 EROFS (Read-only file system)
...
mount("/dev/sr0", "/mnt/sr0", 0x412862, MS_RDONLY|MS_REMOUNT|MS_SILENT|MS_RELATIME, "nojoliet,check=s,map=n,blocksize"...) = 0
Clearly, not what was intended!
