From 5e00d1b5b4c10fb839afd5ce61db8e24339454b0 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 12 Aug 2010 14:31:06 +0200 Subject: [PATCH] BLOCK: fix bio.bi_rw handling Return of the bi_rw tests is no longer bool after commit 74450be1. But results of such tests are stored in bools. This doesn't fit in there for some compilers (gcc 4.5 here), so either use !! magic to get real bools or use ulong where the result is assigned somewhere.
