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
