I have one reservation about this patch series. For example, the changes, - seq_printf(m, "%s", p); + seq_puts(m, p); These calls are not equivalent because the bounds check is not the same. seq_puts will fail when m->count + strlen(p) == m->size. seq_write() does the same check as seq_puts() but the other routines vary. There's a similar situation with the changes, - seq_puts(m, "x"); + seq_putc(m, 'x'); Have you considered what the implications might be? Are there any? -- On Wed, 3 Dec 2014, Rasmus Villemoes wrote: > These patches mostly replace seq_printf with simpler and faster > equivalents, e.g. seq_printf(m, "something") => seq_puts(m, > "something") and seq_printf(m, "\n") => seq_putc(m, '\n).
