[Intel-xe] [PATCH 0/2] drm/xe: Fix unprotected rebind_list accesses

["Thomas Hellström" <thomas.hellstrom@linux.intel.com>]

Each VM has two rebind lists, one protected by the VM resv, the other
one protected essentially by the VM notifier.list_lock. This series
intends to fix two points of illegal access.

Patch 1 fixes an access of VM rebind_lists' link without the VM resv held.
Patch 2 fixes an issue where the VMA may not be removed from the
VM notifier.rebind_list on VMA destruction.

Thomas Hellström (2):
  drm/xe: Fix unlocked access of the vma::rebind_link
  drm/xe: Properly remove the vma from the vm::notifer::rebind_list when
    destroyed
