Erik Kaneda 1e8d218655 ACPICA: Do not increment operation_region reference counts for field units ... [ Upstream commit 6a54ebae6d ] ACPICA commit e17b28cfcc31918d0db9547b6b274b09c413eb70 Object reference counts are used as a part of ACPICA's garbage collection mechanism. This mechanism keeps track of references to heap-allocated structures such as the ACPI operand objects. Recent server firmware has revealed that this reference count can overflow on large servers that declare many field units under the same operation_region. This occurs because each field unit declaration will add a reference count to the source operation_region. This change solves the reference count overflow for operation_regions objects by preventing fieldunits from incrementing their operation_region's reference count. Each operation_region's reference count will not be changed by named objects declared under the Field operator. During namespace deletion, the operation_region namespace node will be deleted and each fieldunit will be deleted without touching the deleted operation_region object.
