[PATCH 3/3] smbios: correctly name Structure Table Maximum Size field

Heinrich Schuchardt heinrich.schuchardt at canonical.com
Thu Feb 1 01:20:22 CET 2024


In the SMBIOS 3 entry point the Structure Table Maximum Size field was
incorrectly named max_struct_size. A Maximum Structure Size field only
exists in the SMBIOS 2.1 entry point and has a different meaning.

Call the Structure Table Length field table_maximum_size.
