Description
An application using external memory may wish to synchronize access to that memory using fences. This extension enables an application to create fences from which non-Vulkan handles that reference the underlying synchronization primitive can be exported.
Promotion to Vulkan 1.1
All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

Issues
This extension borrows concepts, semantics, and language from
VK_KHR_external_semaphore.
That extension’s issues apply equally to this extension.
