-From: d4r Windows port
-Subject: [PATCH] Backport AMD external-memory view ownership fix to ROCm 7.2
-
-Upstream fix: ROCm/clr 529f6b1641de436dafbb095d5438b0fbf773765d
-(ROCm/rocm-systems #3528). Already present in current upstream.
-The constructor owns reference 1. MemObjMap does not retain the view;
-hipFree removes the entry and releases reference 1. The extra retain
-leaks the view and its parent imported allocation.
-
-Hardware regression: d4r_d3d12_hip_interop_probe --interop-mode map
---iterations 64. Windows SDK 7.2.60201 leaks one HANDLE / 256 KiB each
-cycle; tested TheRock 10.2.0a20260929 (HIP 7.17.26386) stays bounded.
-This patch is for rebuilding old runtime sources, never binary patching.
