[PATCH 0/5] Batch of PCI peer-to-peer fixes

From: Leon Romanovsky

Date: Sun Aug 30 2026 - 07:18:29 EST


Hi Bjorn,

These fixes come from my larger series that aligns the code with the PCI
specification regarding the handling of ACS bits [1].

This series has already been reviewed by Logan and Jason.

Thanks,
