You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: zsyscall_linux.go
    path of file: ./repos/gotosocial/vendor/golang.org/x/sys/unix
    
    the code of the file until where you have to start completion: // Code generated by mkmerge; DO NOT EDIT.

//go:build linux

package unix

import (
	"syscall"
	"unsafe"
)

// THIS FILE IS GENERATED BY THE COMMAND AT THE TOP; DO NOT EDIT

func FanotifyInit(flags uint, event_f_flags uint) (fd int, err error) {
	r0, _, e1 := Syscall(SYS_FANOTIFY_INIT, u
    
func mremap(oldaddr uintptr, oldlength uintptr, newlength uintptr, flags int, newaddr uintptr) (xaddr uintptr, err error) {
	r0, _, e1 := Syscall6(SYS_MREMAP, uintptr(oldaddr), uintptr(oldlength), uintptr(newlength), uintptr(flags), uintptr(newaddr), 0)
	xaddr = uintptr(r0)
	if e1 != 0 {
		err = errnoErr(e1)
	}
	return
