[PATCH v4 0/7] PCI: Remove pcim_iounmap_regions()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



OK, so unfortunately it seems very challenging to reconcile the merge
conflict pointed up by Serge between net-next and pci-devres regarding
"ethernet: stmicro": A patch that applies to the net-next tree does not
apply anymore to pci-devres (and vice versa).

So I actually think that it would be best if we just drop the portation
of "ethernet: stmicro" for now and port it as the last user in v6.13.

That should then be trivial.

Changes in v4:
  - Drop the "ethernet: stmicro: [...] patch since it doesn't apply to
    net-next, and making it apply to that prevents it from being
    applyable to PCI ._. (Serge, me)
  - Instead, deprecate pcim_iounmap_regions() and keep "ethernet:
    stimicro" as the last user for now. Perform the deprecation in the
    series' first patch. Remove the Reviewed-by's givin so far to that
    patch.
  - ethernet: cavium: Use PTR_ERR_OR_ZERO(). (Andy)
  - vdpa: solidrun (Bugfix) Correct wrong printf string (was "psnet" instead of
    "snet"). (Christophe)
  - vdpa: solidrun (Bugfix): Add missing blank line. (Andy)
  - vdpa: solidrun (Portation): Use PTR_ERR_OR_ZERO(). (Andy)
  - Apply Reviewed-by's from Andy and Xu Yilun.

Changes in v3:
  - fpga/dfl-pci.c: remove now surplus wrapper around
    pcim_iomap_region(). (Andy)
  - block: mtip32xx: remove now surplus label. (Andy)
  - vdpa: solidrun: Bugfix: Include forgotten place where stack UB
    occurs. (Andy, Christophe)
  - Some minor wording improvements in commit messages. (Me)

Changes in v2:
  - Add a fix for the UB stack usage bug in vdap/solidrun. Separate
    patch, put stable kernel on CC. (Christophe, Andy).
  - Drop unnecessary pcim_release_region() in mtip32xx (Andy)
  - Consequently, drop patch "PCI: Make pcim_release_region() a public
    function", since there's no user anymore. (obsoletes the squash
    requested by Damien).
  - vdap/solidrun:
    • make 'i' an 'unsigned short' (Andy, me)
    • Use 'continue' to simplify loop (Andy)
    • Remove leftover blank line
  - Apply given Reviewed- / acked-bys (Andy, Damien, Bartosz)


Important things first:
This series is based on [1] and [2] which Bjorn Helgaas has currently
queued for v6.12 in the PCI tree.

This series shall remove pcim_iounmap_regions() in order to make way to
remove its brother, pcim_iomap_regions().

@Bjorn: Feel free to squash the PCI commits.

Regards,
P.
