[$] Moving the kernel to modern C

Despite its generally fast-moving nature, the kernel project relies on anumber of old tools. While critics like to focus on the community'sextensive use of email, a possibly more significant anachronism is the useof the 1989 version of the C language standard for kernel code - a standardthat was codified before the kernel project even began over 30 years ago.It is looking like that longstanding practice could be coming to an end assoon as the 5.18 kernel, which can be expected in May of this year.
