Description Vaios Papadimitriou 2010-02-19 16:27:44 UTC 
Description of problem:
The last-submitted LPFC driver version 8.2.0.63.3p for RHEL5.5 inclusion, uses the following symbols that will need to be added to the RHEL5.5 kabi_whitelist:

  pci_request_selected_regions
  pci_release_selected_regions
  pci_disable_pcie_error_reporting
  pci_cleanup_aer_uncorrect_error_status
  pci_select_bars
  fc_vport_create
  pci_enable_pcie_error_reporting


This is the output of the abi_check.py script:

Comment 1 Andrius Benokraitis 2010-02-19 17:05:28 UTC 
We are at the end of RHEL 5.5. Unfortunately this isn't going to make it. Deferring to 5.6.
Comment 2 Joseph Mann 2010-04-30 15:29:37 UTC 
The following symbols are used by LPFC driver version 8.2.0.74.1p for RHEL5.6 inbox inclusion. These symbols will need to be added to the RHEL5.6 kernel api whitelist. (This check was done against the RHEL5.5 GA kernel)

pci_request_selected_regions
pci_release_selected_regions
pci_disable_pcie_error_reporting
pci_cleanup_aer_uncorrect_error_status
pci_select_bars
fc_vport_create
pci_enable_pcie_error_reporting
Comment 3 Jon Masters 2010-08-24 04:53:21 UTC 
Please can you let me know whether you are making this request solely because you intend to have this driver included *within* the RHEL5.6 kernel? If this is the case, this is not a bug, because we do not need all symbols for all internal drivers to be on the whitelist. The drivers internally are self-consistent. Please update this bug, or close it accordingly. Thanks.
