From: Rikard Falkeborn <rikard.falkeborn@xxxxxxxxx> Subject: mm/swap_state: constify static struct attribute_group The only usage of swap_attr_group is to pass its address to sysfs_create_group() which takes a pointer to const attribute_group. Make it const to allow the compiler to put it in read-only memory.
