Using seq_putc to print a single character saves at least a strlen()
call and a memory access, and may also give a small .text reduction.Signed-off-by: Rasmus Villemoes

Using seq_printf to print a simple string is a lot more expensive than
it needs to be, since seq_puts exists. Replace seq_printf with
seq_puts when possible.Signed-off-by: Rasmus Villemoes

SPC-3 defines SERVICE ACTION IN(12) and SERVICE ACTION IN(16).

There's several locations in the kernel that open code the calculation
of the next location in the trace_seq buffer. This is usually done withp->buffer + p->len
Instead of having this open coded, supply a helper function in the
header to do it for them. This function is called trace_seq_buffer_ptr().Link: http://lkml.kernel.org/p/20140626220129.452783019@goodmis.org
