Subject: [PATCH] mellanox: mlx5: Use logging functions to reduce text ~10k/5%
Date: Wed, 22 Jun 2016 11:23:59 -0700	[thread overview]
Message-ID: <1466619839.13093.4.camel@perches.com> (raw)

The logging macros create a bit of duplicated code/text.

Use specialized functions to reduce the duplication.

(defconfig/x86-64)
$ size drivers/net/ethernet/mellanox/mlx5/core/built-in.o*
   text	   data	    bss	    dec	    hex	filename
 178634	   2059	     16	 180709	  2c1e5	drivers/net/ethernet/mellanox/mlx5/core/built-in.o.new
 188679	   2059	     16	 190754	  2e922	drivers/net/ethernet/mellanox/mlx5/core/built-in.o.old

The output changes now do not include line #,
but do include the function offset.
