Oh, and the other nice thing is this in our own code for ext2....

# if EXT2_IFSOCK != S_IFSOCK
                if (EXT2_ISSOCK (mode))
                {
                        ptr->mode &= ~EXT2_IFSOCK;
                        ptr->mode |= S_IFSOCK;
                }
# endif

The above is because if you bring in a filesystem from another Linux
machine that uses EXT2 we have to do conversion. Yuck.

It makes sense to move to this "defacto" standard.
