"man klogd", "man ksymoops".

Short: is an ordered (by address) list of (kernel address, ?type?,
and syscall name).
Module syscalls are dynamic by nature so there's a kernel interface for
exporting symbols to user utilities needing their addresses (see

You don't need to boot. But user space apps like ps (can show
the current syscall used by a process), klogd (for clean GPF reports),
ksymoops (mainly as a cross-check with vmlinux symbols) use it and
search it in numerous places : with or without `-uname -r` appended (at
least in / /boot /usr/src/linux).
