[patch 062/119] mm/page_idle.c: constify attribute_group structures

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arvind Yadav <arvind.yadav.cs@xxxxxxxxx>
Subject: mm/page_idle.c: constify attribute_group structures

attribute_group are not supposed to change at runtime.  All functions
working with attribute_group provided by <linux/sysfs.h> work with const
attribute_group.  So mark the non-const structs as const.
