[PATCH 0/1] MR9695: win32u: Require VK_KHR_external_semaphore_fd for keyed mutexes.

[Rémi Bernon (＠rbernon)]

We need to use vkImportSemaphoreFdKHR to import the keyed mutex sync
object, and it will be NULL if the extension hasn't been enabled.

We need to use vkImportSemaphoreFdKHR to import the keyed mutex sync
object, and it will be NULL if the extension hasn't been enabled.
