This patch set adds fchmodat4(), a new syscall. The actual
implementation is super simple: essentially it's just the same as
fchmodat(), but LOOKUP_FOLLOW is conditionally set based on the flags.
I've attempted to make this match "man 2 fchmodat" as closely as

that can act as both a target for early printk and as the system
