The logic is\napplicable to architectures where the CLOSID effectively forms part of the\nmonitoring identifier and so do not allow complete freedom to choose an unused\nmonitoring identifier for a given CLOSID.\n\nThis support missed that some platforms may not have these counters. This\ncauses a NULL pointer dereference when creating a new control group as the\narray was not allocated by dom_data_init().\n\nAs this feature isn't necessary on platforms that don't have cache occupancy\nmonitors, add this to the check that occurs when a new control group is\nallocated.\n\ud83d\udccf Published: 2025-04-18T07:01:30.421Z\n\ud83d\udccf Modified: 2025-04-18T07:01:30.421Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/a8a1bcc27d4607227088d80483164289b5348293\n2. https://git.kernel.org/stable/c/ed5addb55e403ad6598102bcf546e068ae01fef6\n3. https://git.kernel.org/stable/c/93a418fc61da13d1ee4047d4d1327990f7a2816a\n4. https://git.kernel.org/stable/c/a121798ae669351ec0697c94f71c3a692b2a755b", "creation_timestamp": "2025-04-18T07:59:21.000000Z"} 2025-04-18T07:59:21+00:00
