Tables declared with the ACPI_PROBE_TABLE linker macro are typically traversed by using the start and end symbols created by the linker script. However, there are some APIs that use sentinel-delimited tables (e.g. acpi_match_device). To better support these APIs an additional section is added at the end of the probe table. This section can be used to add a sentinel for tables that require it.
