Subject: [PATCH] GFS2: 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
5259 1344 8 6611 19d3 fs/gfs2/sys.o
File size After adding 'const':
text data bss dec hex filename
5371 1216 8 6595 19c3 fs/gfs2/sys.o
