Subject: [PATCH] qlcnic: make the array random_data static const, makes object smaller
Date: Sun, 1 Aug 2021 16:16:59 +0100 [thread overview]
Message-ID: <20210801151659.146113-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array random_data on the stack but instead it
static const. Makes the object code smaller by 66 bytes.
Before:
text data bss dec hex filename
52895 10976 0 63871 f97f ../qlogic/qlcnic/qlcnic_ethtool.o
After:
text data bss dec hex filename
52701 11104 0 63805 f93d ../qlogic//qlcnic/qlcnic_ethtool.o
(gcc version 10.2.0)
