Can you elaborate why you think this commit is > "utter crap"? A kernel driver has absolutely no business making decissions based on current->comm, which can be changed by any userspace process. This is kernel programming 101. Independent of that a check for a specific program as the callers makes no sense whatsoever as a given program and change over time. This is not even something kernel specific but something that ever software engineer should do. > I'd also appreciate if you could be a bit less aggressive.

I'm just really disappointed by the amoubt of crap that gets shovelled into the kernel and even more disappointed by the abslutely lack of knowledge of some of the contributors.
