[PATCH] loop: constify attribute_group structure
From: Amitoj Kaur Chawla
Date: Wed Aug 02 2017 - 18:59:55 EST
Functions working with attribute_groups provided by <linux/sysfs.h>
work with const attribute_group. These attribute_group structures do not
change at runtime so mark them as const.
File size before:
text data bss dec hex filename
27981 5489 480 33950 849e drivers/block/loop.o
File size after:
text data bss dec hex filename
28320 5421 480 34221 85ad drivers/block/loop.o
This change was made with the help of Coccinelle.
