Subject: [PATCH 2/2] scsi: lpfc: Add logging functions to reduce object size
Date: Mon, 10 Aug 2020 15:59:20 -0700 [thread overview]
Message-ID: <9dc4b3349e67a225e26d2d25e261a5b24a3f92b5.1597100152.git.joe@perches.com> (raw)
In-Reply-To: <cover.1597100152.git.joe@perches.com>
Make functions from logging macros.
Reduces overall object size ~14% (120KB) (x86-64, defconfig, with LPFC)
$ size -t drivers/scsi/lpfc/built-in.a.old
888552 8910 2900 900362 dbd0a (TOTALS)
$ size -t drivers/scsi/lpfc/built-in.a.new
766757 8910 2900 778567 be147 (TOTALS)
Miscellanea:
o Add header #ifdef guards where unused in .h files
