ocfs2: 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 4402 1088 38 5528 1598 fs/ocfs2/stackglue.o File size After adding 'const': text data bss dec hex filename 4442 1024 38 5504 1580 fs/ocfs2/stackglue.o Link: http://lkml.kernel.org/r/cab4e59b4918db3ed2ec77073a4cb310c4429ef5.1498808026.git.arvind.yadav.cs@gmail.com Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Cc: Mark Fasheh <mfasheh@versity.com> Cc: Joel Becker <jlbec@evilplan.org> Cc: Junxiao Bi <junxiao.bi@oracle.com> Cc: Joseph Qi <jiangqi903@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
