proc: constify seq_operations
proc_uid_seq_operations, proc_gid_seq_operations and proc_projid_seq_operations are only called in proc_id_map_open with seq_open as const struct seq_operations so we can constify the 3 structures and update proc_id_map_open prototype. text data bss dec hex filename 6817 404 1984 9205 23f5 kernel/user_namespace.o-before 6913 308 1984 9205 23f5 kernel/user_namespace.o-after Signed-off-by: Fabian Frederick <fabf@skynet.be> Cc: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
