lib/string_helpers.c: constify static arrays
Complement commit 68aecfb97978 ("lib/string_helpers.c: make arrays static") by making the arrays const -- not only pointing to const strings. This moves them out of the data section to the r/o data section: text data bss dec hex filename 1150 176 0 1326 52e lib/string_helpers.old.o 1326 0 0 1326 52e lib/string_helpers.new.o Signed-off-by: Mathias Krause <minipli@googlemail.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
