I've pushed a patch to clarify just what can_blit() is trying to test:

    sna/dri: Cleanup validation of blit extents

    Prompted by a suggestion by Haihao, clarify the intent behind checking
    the incoming maximum blit extents against the recorded sizes of the
    attached bo. Due to the asynchronous nature of DRI2 invalidation, it is
    possible for the DRI2 buffer to be stale and for its bo to be smaller
    than required for the client's blit.
