Subject: [PATCH] net: 3c509: make the array if_names static const, makes object smaller
Date: Sun, 1 Aug 2021 16:26:50 +0100 [thread overview]
Message-ID: <20210801152650.146572-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array if_names on the stack but instead it
static const. Makes the object code smaller by 99 bytes.
Before:
text data bss dec hex filename
27886 10752 672 39310 998e ./drivers/net/ethernet/3com/3c509.o
After:
text data bss dec hex filename
27723 10816 672 39211 992b ./drivers/net/ethernet/3com/3c509.o
(gcc version 10.2.0)
