[PATCH 0/6] constify pci_error_handlers structures

[Julia Lawall]

These pci_error_handlers structures are only stored in the err_handler
field of a pci_driver structure, and this field is declared as const.  Thus
the pci_error_handlers structures can be const too.

Done with the help of Coccinelle.

If you're doing a scripted conversion of the pci_error_handlers
structured I'd much rather see that structure killed off and folded
into the pci_driver one.

OK, sure.  So to be precise, you want the fields error_detected,
mmio_enabled, etc to be added as new fields to the pci_driver structure?

They both have a resume field, though.  What should the pci_error_handlers
resume function be renamed to?  Would resume_after_error be too much?

error_resume maybe?

FYI, I already killed it for the PCIe port drivers a while ago:

Re: [PATCH 0/6] constify pci_error_handlers structures

[Julia Lawall]

Another issue arises in the files drivers/infiniband/hw/hfi1/pcie.c and
drivers/infiniband/hw/qib/qib_pcie.c, where the pci_error_handlers
structure is defined in one file and used in another file.  The structure
definition references various functions that are static in the same file.
Should I try to move those functions to the file containing the pci_driver
structure?  Or leave the functions where they are and remove the static
annotation?

thanks,
julia

Re: [PATCH 0/6] constify pci_error_handlers structures

[Julia Lawall]

Another issue arises in the files drivers/infiniband/hw/hfi1/pcie.c and
drivers/infiniband/hw/qib/qib_pcie.c, where the pci_error_handlers
structure is defined in one file and used in another file.  The structure
definition references various functions that are static in the same file.
Should I try to move those functions to the file containing the pci_driver
structure?  Or leave the functions where they are and remove the static
annotation?

thanks,
julia

I'd just leave them as-is and remove the static for now.

Fine with me. Thanks for the contribution.
