[PATCH V3 0/5] nvme-trace: Add support for fabrics command

[Minwoo Im]

Hi,

Here's a third patchset to support fabrics command tracing.  The first
patch updated host/trace module to a outside of it to provide common
interfaces for host and target both.  The second one adds support for
tracing fabrics command from host-side.  The third is a trivial clean-up
for providing a helper function to figure out given command structure is
for fabrics or not.

The fourth and fifth are the major change points of this patchset.  4th
patch adds request tracing from the target-side.  5th updated, of course,
completion of given request.

Please review.
Thanks,

Changes to V2:
  - Provide a common code for both host and target. (Chaitanya)
  - Add support for tracing requests in target-side (Chaitanya)
  - Make it simple in trace.h without branch out from nvme core module
    (Christoph)

Changes to V1:
  - fabrics commands should also be decoded, not just showing that it's
    a fabrics command. (Christoph)
  - do not make it within nvme admin commands (Chaitanya)

Minwoo Im (5):
  nvme: Make trace common for host and target both
  nvme-trace: Support tracing fabrics commands from host-side
  nvme: Introduce nvme_is_fabrics to check fabrics cmd
  nvme-trace: Add tracing for req_init in trarget
  nvme-trace: Add tracing for req_comp in target
