From 8ffdc6550c47f75ca4e6c9f30a2a89063e035cf2 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 6 Jan 2006 09:49:03 +0100 Subject: [BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn() add @uptodate argument to end_that_request_last() and @error to rq_end_io_fn(). there's no generic way to pass error code to request completion function, making generic error handling of non-fs request difficult (rq->errors is driver-specific and each driver uses it differently). this patch adds @uptodate to end_that_request_last() and @error to rq_end_io_fn(). for fs requests, this doesn't really matter, so just using the same uptodate argument used in the last call to end_that_request_first() should suffice. imho, this can also help the generic command-carrying request jens is working on.
