Comment 22 for bug 41624

Which kernel you are using does not really matter because the linux kernel developers consider this to be working as intended. I have tried arguing with the on the LKML a few times with no success. They seem to think that the read only mount flag does not mean "do not write to this disk" but rather "do not allow files to be opened for write access".

If we want this fixed, we're going to have to fix it ourselves it looks like.
