Subject: [PATCH blktrace v2 00/22] blktrace: Add user-space support for zoned command tracing

This patch series extends the user-space blktrace tools to support the new
trace events for zoned block device commands introduced in the corresponding
kernel patch series.

The updates include:

- Introduction of a new ioctl requesting the v2 version of the trace
- Definitions for new zoned operation trace events.
- Parsing support in blkparse for these events.
- Display of the new events with clear labeling (e.g., ZO, ZA, ZR).
- Backward-compatible changes that do not affect existing functionality.

These changes complement the kernel patches and allow full visibility into
zone management commands in blktrace output, enabling better analysis and
debugging of zoned storage workloads.

The updated blktrace utility will first issue the BLKTRACESETUP2 ioctl and if
it fails transpartently fall back to BLKTRACESETUP allowing backwards
compatibility.

Feedback and testing on additional device types are appreciated.

Changes to v1:
- Incorporated feedback from Chaitanya
- Add patch fixing a compiler warning at the beginning
