  "message": "[native] Fix data race in subgroup matrix tests\n\nFixes failing MatrixMatrixArithmeticTest tests for\nMatrixMultiplyAccumulate ops. If subgroups \u003c MaxSubgroups, then multiple\nsubgroups would read/write from the same memory location. Fixed by only\nexecuting the shader for subgroup_id 0.\n\nThanks to Jesse Natalie from Microsoft for pointing this bug out.\n\nBug: 525517826\nChange-Id: I34166b243c5642b95ec7ffdc792c6bc6d581c8d1\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/323916\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\nCommit-Queue: Antonio Maiorano \u003camaiorano@google.com\u003e\nReviewed-by: Alan Baker \u003calanbaker@google.com\u003e\n",
