From 1822952ba2b9f22f79019d07ebbeca31dc14b718 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 11 May 2009 17:56:07 +0900 Subject: [PATCH] block: let blk_end_request_all handle bidi requests blk_end_request_all() and __blk_end_request_all() should finish all bytes including bidi, by definition. That's what all bidi users need , bidi requests must be complete as a whole (partial completion is impossible).
