I did notice that attempt_merge() calls elv_merge_requests() (not to be confused with elv_merged_request()) if it merges the requests. So it seems there is elv_merge_requests() which means the request was merged, and elv_merged_request() which means the request was *not* merged... I have no idea what is going on there :-( > This patch itself looks good to me. > > Reviewed-by: Nathan Huckleberry <nhuck@xxxxxxxxxx> Thanks. Jens, Christoph, etc., anyone else want to take a look too? - Eric
