From 21bb3093e6accd2d7d60531a472a34e40911acd9 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 12 Jul 2016 16:54:03 +1000 Subject: [PATCH] vfio/spapr: Remove stale ioctl() call This ioctl() call to VFIO_IOMMU_SPAPR_TCE_REMOVE was left over from an earlier version of the code and has since been folded into vfio_spapr_remove_window(). It wasn't caught because although the argument structure has been removed, the libc function remove() means this didn't trigger a compile failure. The ioctl() was also almost certain to fail silently and harmlessly with the bogus argument, so this wasn't caught in testing.
