  "message": "physmem: Support coordinated discarding of RAM with guest_memfd\n\nA new field, attributes, was introduced in RAMBlock to link to a\nRamBlockAttributes object, which centralizes all guest_memfd related\ninformation (such as fd and status bitmap) within a RAMBlock.\n\nCreate and initialize the RamBlockAttributes object upon ram_block_add().\nMeanwhile, register the object in the target RAMBlock\u0027s MemoryRegion.\nAfter that, guest_memfd-backed RAMBlock is associated with the\nRamDiscardManager interface, and the users can execute RamDiscardManager\nspecific handling. For example, VFIO will register the\nRamDiscardListener and get notifications when the state_change() helper\ninvokes.\n\nAs coordinate discarding of RAM with guest_memfd is now supported, only\nblock uncoordinated discard.\n\nTested-by: Alexey Kardashevskiy \u003caik@amd.com\u003e\nReviewed-by: Alexey Kardashevskiy \u003caik@amd.com\u003e\nAcked-by: David Hildenbrand \u003cdavid@redhat.com\u003e\nSigned-off-by: Chenyi Qiang \u003cchenyi.qiang@intel.com\u003e\nLink: https://lore.kernel.org/r/20250612082747.51539-6-chenyi.qiang@intel.com\nSigned-off-by: Peter Xu \u003cpeterx@redhat.com\u003e\n",
