* scsi: print single-character strings with seq_putcRasmus Villemoes2015-02-021-1/+1
| | | | | | | | | 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_putsRasmus Villemoes2015-02-021-3/+3
| | | | | | | | | | 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_16Hannes Reinecke2014-11-241-1/+1
| | | | | | | | | | | 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 functionSteven Rostedt (Red Hat)2014-07-011-8/+8
| | | | | | | | | | | | | | | 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().
