dm space map metadata: constify dm_space_map structures
Declare dm_space_map structures as const as they are only passed as an argument to the function memcpy. This argument is of type const void *, so dm_space_map structures having this property can be declared as const. File size before: text data bss dec hex filename 4889 240 0 5129 1409 dm-space-map-metadata.o File size after: text data bss dec hex filename 5139 0 0 5139 1413 dm-space-map-metadata.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
