I think these patches are a waste of time and a resources. It would be different if your patches fixed actual bugs. This is just mindless code transformations that MAY in the best case save a few bytes of code here and there (I don't know; you didn't say). But the potential gains from these incredibly numerous and tiny patches that don't fix anything are so small, it's a waste of time, bandwidth, and mental capacity for you and for everybody involved. I just searched my inbox for patches from you and you sent literally _hundreds_ over the past few days, all doing this crazy printf/puts/putc transformation. Another bit of searching and I see that I'm not the first one giving you this response: https://lkml.org/lkml/2017/1/23/383 - Jens Axboe https://lkml.org/lkml/2017/1/23/262 - Johannes Thumshirn https://lkml.org/lkml/2017/1/12/513 - Cyrille Pitchen https://lkml.org/lkml/2016/10/24/491 - Theodore Ts'o https://lkml.org/lkml/2016/10/7/148 - Dan Carpenter https://lkml.org/lkml/2016/9/14/58 - Christian Borntraeger ...and I'm sure there are many more.
