drm/i915/gem: Limit struct_mutex to eb_reserve We only need to serialise the multiple pinning during the eb_reserve phase. Ideally this would be using the vm->mutex as an outer lock, or using a composite global mutex (ww_mutex), but at the moment we are using struct_mutex for the group. Closes: https://gitlab.freedesktop.org/drm/intel/issues/1381 Fixes: 003d8b9143a6 ("drm/i915/gem: Only call eb_lookup_vma once during execbuf ioctl") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200306071614.2846708-3-chris@chris-wilson.co.uk
