We put big pile once the driver was functional and nobody expected it to be merged into stable kernel from that point we post everything that is mergable. The patches are sent out each Friday after they got through internal review there is nothing, there is nothing magical about it.

Unfortunately fixing bugs on stable branch take precedence of adjusting to new API on development branch that someone decided to do. I wanted to work directly on wireless testing but it was broken over an over and I have only limited resources more in testing then in development I just had to branch out to be ready with the driver when HW is out. People just check the immediate impact of they fix the don't test for collateral damage and this is understandable an individual developer doesn't have lab with IBSS, BSS, AP, etc setups. > That would also avoid the nasty surprises you've gotten a few times > where other people managed to get patches to iwlwifi drivers into the > Linux tree without you noticing. I've noticed just deferred to fixing it. In summary This was my first Linux project, it was first project that was done on new HW (nobody could test it but us) and I don't deny I did a lot of mistake in development process I don't deny that and we are learning from them.
