scsi: print single-character strings with seq_putc

2015-02-02T17:57:46+00:00

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.

scsi: replace seq_printf with seq_puts

2015-02-02T17:57:45+00:00

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.

scsi: rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16

2014-11-24T19:01:40+00:00

SPC-3 defines SERVICE ACTION IN(12) and SERVICE ACTION IN(16).
So rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 to be
consistent with SPC and to allow for better distinction.

tracing: Add trace_seq_buffer_ptr() helper function

2014-07-01T11:13:39+00:00

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 with

  p->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().
