  "message": "arm64/gcs: release GCS on failed fork\n\ncopy_thread() can map a CLONE_VM GCS and still return 0. A later\ncopy_process() failure calls exit_thread(), but arm64 did not\nimplement it, so the VMA stayed in the parent\u0027s mm. Wire\nHAVE_EXIT_THREAD to gcs_free().\n\nKernel threads created with CLONE_VM (io_uring and vhost workers)\ninherit the parent\u0027s gcs_base/gcs_size from arch_dup_task_struct()\nwithout allocating their own GCS. When such a thread exits,\nexit_mm() -\u003e mm_release() -\u003e deactivate_mm() -\u003e gcs_free() unmaps the\nparent\u0027s GCS. With the new exit_thread(), a failed copy_process() for\none of these threads would do the same. Clear these fields in\ncopy_thread().\n\nFixes: 506496bcbb42 (\"arm64/gcs: Ensure that new threads have a GCS\")\nCc: stable@vger.kernel.org\nCc: Mark Brown \u003cbroonie@kernel.org\u003e\nAssisted-by: LLM\nSigned-off-by: Iván Ezequiel Rodriguez \u003civanrwcm25@gmail.com\u003e\nReviewed-by: Mark Brown \u003cbroonie@kernel.org\u003e\nTested-by: Mark Brown \u003cbroonie@kernel.org\u003e\nSigned-off-by: Catalin Marinas \u003ccatalin.marinas@arm.com\u003e\n",
