  "message": "remove global device lock for host-mapped-pointer buffers\n\nThis makes creation of these buffers thread-safe without\ntaking the global device lock. Note that destroying the\ndevice while creating any resource is still not safe.\n\nTested on Linux with TSAN, that the implementation is\ndata-race free.\n\nOn d3d12, buffer creation:\n - uses the D3D12 device, which is thread-safe\n - uses the ResidencyManager which is MutexProtected\n - reads lots of device info/toggles; which are immutable\n   after creation\n\nOn d3d12, buffer destruction\n - uses the deallocation queue which is MutexProtected\n - uses the callback task queue which is MutexProtected\n\nOn metal, buffer creation\n - uses the MTLDevice which is already thread-safe\n\nOn metal, buffer description\n - uses the callback task queue which is MutexProtected\n\nOn Vulkan, buffer creation\n - allocates with the VkDevice, which is thread-safe\n - reads lots of device state which is immutable after\n   creation\n - uses the resource memory allocator which is MutexProtected\n\nOn vulkan, buffer destruction\n - uses the resource memory allocator which is MutexProtected\n - uses the fenced deleter which is MutexProtected\n - uses the callback task queue which is MutexProtected\n\nBug: dawn:1662\nChange-Id: Ib0962a5f8afcc4b80a8f3d759d8ad80bf28c8094\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/175208\nReviewed-by: Loko Kung \u003clokokung@google.com\u003e\nKokoro: Kokoro \u003cnoreply+kokoro@google.com\u003e\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\nCommit-Queue: Austin Eng \u003cenga@chromium.org\u003e\n",
