[PATCH 0/2] tools: Fix tools/virtio test build

[Yichong Chen]

This series fixes build failures hit by:

  make -C tools/virtio test

Patch 1 adds tools/virtio compatibility definitions needed by
recent virtio headers when building vhost_net_test.

Patch 2 makes tools/include/linux/overflow.h include stdint.h
for SIZE_MAX, which is used by its size helper functions.

With the series applied, make -C tools/virtio test builds
virtio_test, vringh_test and vhost_net_test successfully.

Yichong Chen (2):
  tools/virtio: Add missing compat definitions for vhost_net_test
  tools/include: Include stdint.h for SIZE_MAX in overflow.h

Hi Michael,

I checked the history again. The tree was based on v7.1, but I had
unrelated local commits on top when I generated the series.

I rechecked this on a clean v7.1 tree:

  8cd9520d35a6 ("Linux 7.1")

The build failure is still reproducible with:

  make -C tools/virtio test

The first failure is:

  include/linux/virtio.h:10:10: fatal error:
  linux/mod_devicetable.h: No such file or directory

The two patches also apply cleanly on top of v7.1 and make
the tools/virtio test target build virtio_test, vringh_test and
vhost_net_test.

I can resend a v2 based on v7.1 with a base-commit if you prefer.

Thanks,
Yichong

Hello, thanks for the report!
the commit to try is 8cb2c9285e4ce9154f45fb15633ebd45dfd8d9cf - that is
not in 7.1.
