[PATCH v2 3/9] rxrpc: delete these unnecessary static variables n_65535, four, max_500, etc
From: wenyang . linux
Date: Sat Mar 09 2024 - 05:32:13 EST
From: Wen Yang <wenyang.linux@xxxxxxxxxxx>
Delete unnecessary static variables(n_65535, four, max_500, etc.)
and encode them directly in the table entry.
