I considered this, too[1]. However I checked for existing usages of
force_page_cache_readahead() noticed they just ignore the return value
like I did in my patch, so I followed existing convention for this
function. I didn't find any suggestion in Documentation/CodingStyle
for this.

Thanks for looking at this.
