Subject: [PATCH v2 1/3] staging: lustre: 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
9489 992 40 10521 2919 lustre/lustre/osc/lproc_osc.o
1289 288 0 1577 629 lustre/lustre/lmv/lproc_lmv.o
3794 928 40 4762 129a lustre/lustre/lov/lproc_lov.o
3802 576 40 4418 1142 lustre/lustre/mdc/lproc_mdc.o
File size After adding 'const':
text data bss dec hex filename
9553 928 40 10521 2919 lustre/lustre/osc/lproc_osc.o
1353 224 0 1577 629 lustre/lustre/lmv/lproc_lmv.o
3858 864 40 4762 129a lustre/lustre/lov/lproc_lov.o
