I happen to have this lying around. It's trivial but might save you a few minutes work.
static int l_statfs(lua_State *L)
{
struct statfs s;
const char *fname;
int r = 0;
fname = luaL_checkstring(L, 1);
r = statfs(fname, &s);
if(r == -1) {
lua_pushnil(L);
lua_pushstring(L, strerror(errno));
return 2;
}
lua_newtable(L);
lua_pushstring(L, "type"); lua_pushnumber(L, s.f_type); lua_settable(L, -3);
lua_pushstring(L, "bsize"); lua_pushnumber(L, s.f_bsize); lua_settable(L, -3);
lua_pushstring(L, "blocks"); lua_pushnumber(L, s.f_blocks); lua_settable(L, -3);
lua_pushstring(L, "bfree"); lua_pushnumber(L, s.f_bfree); lua_settable(L, -3);
lua_pushstring(L, "bavail"); lua_pushnumber(L, s.f_bavail); lua_settable(L, -3);
lua_pushstring(L, "files"); lua_pushnumber(L, s.f_files); lua_settable(L, -3);
lua_pushstring(L, "ffree"); lua_pushnumber(L, s.f_ffree); lua_settable(L, -3);
lua_pushstring(L, "namelen"); lua_pushnumber(L, s.f_namelen ); lua_settable(L, -3);
return 1;
}
