From b9ec0339d8e22cadf2d9d1b010b51dc53837dfb0 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Tue, 16 Oct 2007 23:29:54 -0700 Subject: add consts where appropriate in fs/nls/* Add const modifiers to a few struct nls_table's member pointers in include/linux/nls.h and adds a lot of const's in fs/nls/*.c files. Resulting changes as visible by size: text data bss dec hex filename 113612 481216 2368 597196 91ccc nls.org/built-in.o 593548 3296 288 597132 91c8c nls/built-in.o Apparently compiler managed to optimize code a bit better because of const-ness. No other changes are made.
