From d064d9f381b00538e41f14104b88a1ae85d78865 Mon Sep 17 00:00:00 2001 From: Bogdan Purcareata Date: Fri, 3 Apr 2015 11:01:54 +0000 Subject: nbd/trivial: fix type cast for ioctl This fixes ioctl behavior on powerpc e6500 platforms with 64bit kernel and 32bit userspace. The current type cast has no effect there and the value passed to the kernel is still 0. Probably an issue related to the compiler, since I'm assuming the same configuration works on a similar setup on x86. Also ensure consistency with previous type cast in TRACE message.
