syncfs returns int (or long?)

[Simone Piccardi <piccardi-TuvemuYfxVQ1GQ1Ptb7lUw@public.gmane.org>]

In man 2 syncfs (version 2011-09-07, also in the website) it is declared as:

void syncfs(int fd);

but then is said:

RETURN VALUE
       syncfs() returns 0 on success; on error, it returns -1 and
       sets  errno to indicate the error.

so it cannot be void. I get

piccardi@monk:/usr/src/linux-source-3.1$ grep -r syncfs include/*
include/asm-generic/unistd.h:#define __NR_syncfs 267
include/asm-generic/unistd.h:__SYSCALL(__NR_syncfs, sys_syncfs)
include/linux/syscalls.h:asmlinkage long sys_syncfs(int fd);

So it seems to be at least long.
