[PATCH v2 0/1] MR3188: winevulkan: Keep deferred operation function params alive.

[Georg Lehmann (＠DadSchoorse)]

The Vulkan spec says:
Parameters to the command requesting a deferred operation may be accessed by the implementation at any time until the deferred operation enters the
complete state Pointer parameters must not be modified (e.g. reallocated/freed).

This fixes a regression in Doom Eternal with ray tracing enabled with drivers
that actually support deferred operations (e.g. nvidia, amdvlk).

[PATCH v2 1/1] winevulkan: Keep deferred operation function params alive.

[Georg Lehmann]

From: Georg Lehmann

The Vulkan spec says:
Parameters to the command requesting a deferred operation may be accessed by the implementation at any time until the deferred operation enters the
complete state. Pointer parameters must not be modified (e.g. reallocated/freed).

This fixes a regression in Doom Eternal with ray tracing enabled with drivers
that actually support deferred operations (e.g. nvidia, amdvlk).
