  "message": "unix: add CPUSetDynamic for systems with more than 1024 CPUs\n\nThe existing CPUSet type is a fixed-size array limited to 1024 CPUs,\nwhich makes it problematic to use for large systems (such as Google\u0027s\nX4 instances with 1440 and 1920 vCPUs), see e.g.\nhttps://github.com/opencontainers/runc/issues/5023.\n\nIntroduce CPUSetDynamic type and NewCPUSet constructor to support large\nsystems. The bit-managing routines (set/clear/isset/fill/count) are\nseparated and reused.\n\nAdd variants of SchedGetaffinity, SchedSetaffinity and SetMemPolicy\nthat accept the new type.\n\nAmend the documentation for CPUSet.\n\nAmend the existing TestSchedSetaffinity to:\n - test set.Fill;\n - use t.Cleanup to restore the affinity.\n\nAdd tests for new functionality (mostly a copy of existing tests).\n\nThis is an alternative to CL 727540 / CL 727541.\n\nCo-Authored-By: Claude Sonnet 4.5 \u003cnoreply@anthropic.com\u003e\nChange-Id: I51bba0305b8dfa7a88a4e7fb8758d73f798574f1\nReviewed-on: https://go-review.googlesource.com/c/sys/+/735380\nReviewed-by: Tobias Klauser \u003ctobias.klauser@gmail.com\u003e\nReviewed-by: David Chase \u003cdrchase@google.com\u003e\nReviewed-by: Michael Pratt \u003cmpratt@google.com\u003e\nLUCI-TryBot-Result: Go LUCI \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\n",
