You sent vast amount of patches, all separate, making it very difficult
to track and respond in efficient way. Do not do that.
Group your work per subsystem.
You were asked to clarify and respond to incorrect fixes statement. I do
not see how you clarified and responded at all.
Best regards,
Krzysztof
