  "message": "VkDevice: Fix sample cache hash collisions that caused spurious test failures.\n\nKeying off a single size_t is likely to cause collisions, more so when the hash function is simple shift-xors of 3 32-bit integers.\n\nUse a proper cache key comparision and a better hash function while we\u0027re at it.\n\nBug: b/137649247\nChange-Id: I1e0deefb0976102714d43dcb9dcedf6aa809bf7f\nReviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/34909\nTested-by: Nicolas Capens \u003cnicolascapens@google.com\u003e\nReviewed-by: Nicolas Capens \u003cnicolascapens@google.com\u003e\nReviewed-by: Chris Forbes \u003cchrisforbes@google.com\u003e\nKokoro-Presubmit: kokoro \u003cnoreply+kokoro@google.com\u003e\n",
