From 6712ecf8f648118c3363c142196418f89a510b90 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 27 Sep 2007 12:47:43 +0200 Subject: Drop 'size' argument from bio_endio and bi_end_io As bi_end_io is only called once when the reqeust is complete, the 'size' argument is now redundant. Remove it. Now there is no need for bio_endio to subtract the size completed from bi_size. So don't do that either. While we are at it, change bi_end_io to return void.
