Subject: [PATCH] scsi: ips: make array 'options' static const, makes object smaller
Date: Fri, 6 Sep 2019 17:45:22 +0100 [thread overview]
Message-ID: <20190906164522.5644-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array 'options' on the stack but instead make it
static const. Makes the object code smaller by 143 bytes.
Before:
text data bss dec hex filename
94483 11272 1184 106939 1a1bb drivers/scsi/ips.o
After:
text data bss dec hex filename
94244 11368 1184 106796 1a12c drivers/scsi/ips.o
(gcc version 9.2.1, amd64)
