Description

In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix VM_BIND UNMAP locking Wrong argument meant that the objs involved in UNMAP ops were not always getting locked. Since _NO_SHARE objs share a common resv with the VM (which is always locked) this would only show up with non-_NO_SHARE BOs. Patchwork: https://patchwork.freedesktop.org/patch/713898/
