Batch of PCI peer-to-peer fixes

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

Posted by Leon Romanovsky 3 weeks, 6 days ago

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,

      PCI/P2PDMA: Do not tear down the allocate attribute on registration failure
      PCI/P2PDMA: Wait for RCU readers before freeing state
      PCI/P2PDMA: Restrict the p2pmem search to pool backed providers
      PCI/P2PDMA: Safely terminate ACS redirect lists
      PCI/P2PDMA: Gate the host bridge whitelist warning on verbose

Bjorn,

Can we please make progress on this series? I need it to be applied so
that I can send my "Fix ACS ..." series with an upstream base commit.
This will allow Sashiko to apply and review it.

Thanks

Applied to pci/p2pdma for v7.4, thanks!
