It really doesn't matter. As if it is "full" or overflowed, the buffer currently gets discarded regardless. Thus, it could mean that the buffer was already overflowed. Because the current logic is full == overflowed. Really, a full buffer is a buffer with all but one byte left used. If size == len, then it has indeed overflowed. That is what my other patch changes. I'll change the comment about that. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
