Subject: [PATCH] net/mlx4: make the array states static const, makes object smaller
Date: Sun, 1 Aug 2021 16:37:42 +0100 [thread overview]
Message-ID: <20210801153742.147304-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Don't populate the array states on the stack but instead it
static const. Makes the object code smaller by 79 bytes.
Before:
text data bss dec hex filename
21309 8304 192 29805 746d drivers/net/ethernet/mellanox/mlx4/qp.o
After:
text data bss dec hex filename
21166 8368 192 29726 741e drivers/net/ethernet/mellanox/mlx4/qp.o
(gcc version 10.2.0)
