fs/seq_file.c: delete small-value optimization num_to_str() optimizes printing small integers [0..9], so the same check higher in callchain is unnecessary. --------------------------------------------------- Is removing this optimization really the same speed? I don't think so. The num_to_str call still does multiple moves of memory to the output, this is a single byte copy.
