Subject: [PATCH] mwifiex: make const array tos_to_ac static, reduces object code size
Date: Tue, 19 Sep 2017 22:05:00 +0100 [thread overview]
Message-ID: <20170919210500.31330-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the read-only const array tos_to_ac on the stack,
instead make it static. Makes the object code smaller by 250 bytes:
Before:
text data bss dec hex filename
26104 2720 128 28952 7118 wmm.o
After:
text data bss dec hex filename
25758 2816 128 28702 701e wmm.o
