From 303d0b0031d6e18a31e95579cb21d712fac5499e Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 14 Apr 2009 16:27:36 +0200 Subject: [PATCH] qemu-cvs-ioctl_nodirection the direction given in the ioctl should be correct so we can assume the communication is uni-directional. The alsa developers did not like this concept though and declared ioctls IOC_R and IOC_W even though they were IOC_RW.
