2023-01-16Currently we disable kbind(2) for static program from libc.a'sPhilip Guenther
preinit hook. Delete that and instead have the kernel disable kbind at exec-time if the program doesn't have an ELF interpreter.

2022-12-30add history for getpid(2) and getppid(2)Jonathan Gray
getpid() appeared (undocumented) in v5. Between v6 and v7 there is an extra return value for the parent process ID. getppid() did not appear in v7, it appeared in 32v libc. But getppid() predates 32v. It seems to have been in earlier USG releases such as Generic 3 (PG-1C300 Issue 3) as the MERT Release 0 manual references it. getppid() didn't become a system call until 4.3BSD-Reno omit most of these details and just mention v5 and 32v with and ok schwarze@
