[patch 061/115] zram: constify attribute_group structures.

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

 



From: Arvind Yadav <arvind.yadav.cs@xxxxxxxxx>
Subject: zram: constify attribute_group structures.

attribute_groups are not supposed to change at runtime.  All functions
working with attribute_groups provided by <linux/sysfs.h> 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
