# DPDK Patch Review

## Analysis

This patch addresses a build failure when compiling with old Linux system headers that lack the `__counted_by` attribute. The fix reorders header includes so that the imported UAPI headers (which contain compatibility definitions) are included before system headers.

## Findings

### Errors

None.

### Warnings

None.

### Info

**Include order follows DPDK conventions:** The patch correctly places the imported UAPI headers first, before system headers. While the DPDK style guide specifies system/libc includes before DPDK includes, this is a special case where the imported headers must come first to provide compatibility definitions. The comment in the commit message explains the technical reason clearly.

**Duplicate Acked-by tag:** The patch contains:
```
Acked-by: David Marchand <david.marchand at redhat.com>
Acked-by: Bruce Richardson <bruce.richardson at intel.com>
Acked-by: David Marchand <david.marchand at redhat.com>
```
David Marchand's Acked-by appears twice. This is a minor redundancy but not a code issue.

## Summary

The patch is technically correct. The include reordering is the appropriate fix for the compilation failure described. The code changes are minimal and focused on solving the stated problem. The commit message provides sufficient context about why this unconventional include order is necessary.

Review-Result: CLEAN
