Ani Sinha June 26, 2023, 1:53 p.m. UTC
Patches 1-4:
Fix tests so that devices do not use non-zero slots on the pcie root
ports. PCIE ports only have one slot, so PCIE devices can only be
plugged into slot 0 on a PCIE port.

Patch 5:
Enforce only one slot on PCIE port.

The test fixes must be applied before the QEMU change that checks for use
of a single slot in PCIE port.

Changelog:
v4: reword commit log for patch 4.
v3: tags added. reword the error description in patch 5. Reword commit log in patch 4. 
v2: add hd-geo-test fix as well as the actual QEMU code fix to the patchset.
The patches are added in the right order.

Btw, the libvirt guys does this better in this respect I think. The maintainer takes the patchset but if small rework in commit logs or comments etc is needed, the maintainer does this himself and pushes the patch. That way there is less churn.

I can do that too sometimes. I'm less of a dictator, prefer to get
acks from others :)

Oh, missed that. it's ok then, just make this a bit more prominent:
note: no changes to patches, just commit log tweaks.
