From bc1bb362334ebc4c65dd4301f10fb70902b3db7d Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Mon, 10 Jul 2017 15:50:15 -0700 Subject: zram: constify attribute_group structures. attribute_groups are not supposed to change at runtime. All functions working with attribute_groups provided by work with const attribute_group. So mark the non-const structs as const. File size before: text data bss dec hex filename 8293 841 4 9138 23b2 drivers/block/zram/zram_drv.o File size After adding 'const': text data bss dec hex filename 8357 777 4 9138 23b2 drivers/block/zram/zram_drv.o Link: http://lkml.kernel.org/r/65680c1c4d85818f7094cbfa31c91bf28185ba1b.1499061182.git.arvind.yadav.cs@gmail.com Signed-off-by: Arvind Yadav Acked-by: Minchan Kim Cc: Sergey Senozhatsky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/block/zram/zram_drv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers') diff --git a/drivers/block/zram/zram_drv.c b/drivers/block/zram/zram_drv.c index d3e3af22a088..856d5dc02451 100644 --- a/drivers/block/zram/zram_drv.c +++ b/drivers/block/zram/zram_drv.c @@ -1124,7 +1124,7 @@ static struct attribute *zram_disk_attrs[] = { NULL, }; -static struct attribute_group zram_disk_attr_group = { +static const struct attribute_group zram_disk_attr_group = { .attrs = zram_disk_attrs, }; -- cgit v1.2.3-58-ga151
