  [PATCH 3/4] scsi: scsi_transport_fc: constify attribute_group structures. Arvind Yadav <arvind.yadav.cs@gmail.com> - 2017-07-14 10:30 +0200

#1687153 — [PATCH 3/4] scsi: scsi_transport_fc: constify attribute_group structures.

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

File size before:
   text	   data	    bss	    dec	    hex	filename
  34122	   1932	      4	  36058	   8cda	drivers/scsi/scsi_transport_fc.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  34186	   1868	      4	  36058	   8cda	drivers/scsi/scsi_transport_fc.o
