From c62f40bfb26356bb289267f3b802ec0434fdc118 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 14 Feb 2018 22:35:43 +0000 Subject: [PATCH] scsi: scsi_transport_spi: make two const arrays static, shrinks object size Don't populate the const read-only arrays spi_test_unit_ready and spi_test_unit_ready on the stack but instead make them static. Makes the object code smaller by over 100 bytes: Before: text data bss dec hex filename 40171 12832 128 53131 cf8b drivers/scsi/scsi_transport_spi.o After: text data bss dec hex filename 39922 12976 128 53026 cf22 drivers/scsi/scsi_transport_spi.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King Signed-off-by: Martin K.
