[Qemu-devel] [PATCH 05/17] linux-user: fix BLK ioctl arguments |
Date: |
Fri, 6 Apr 2012 19:35:05 +0300 |
From: Alexander Graf <address@hidden>
Some BLK ioctls passed sizeof(x) into a macro that already did sizeof() on
the passed in argument, rendering the size information inside the ioctl be
the size of the host default integer type.
