Description Jon Masters 2010-09-02 19:13:44 UTC 
Description of problem:

We are shipping a kspice-usb driver on the RHEL6.0 Supplementary media. This driver is not currently in-tree, though it may be in due course. Of the 70 symbols required by that module in the current instance, the following symbols are not on the approved whitelists and would, ideally, be added to aid in our packaging and distribution of this module (both x86_64 and i686 have been checked and are the only targets required):

bus_register_notifier
bus_unregister_notifier
usb_free_urb
usb_get_urb
usb_register_driver
vmalloc_to_pfn

Note that usb_alloc_urb is already on the whitelist. The exact ABI use of these drivers for i686 and x86_64 is attached to this bug.

Jon.

Comment 6 RHEL Program Management 2010-10-05 01:56:18 UTC 
This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux maintenance release. Product Management has 
requested further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed 
products. This request is not yet committed for inclusion in an Update release.
Comment 9 Jon Masters 2011-02-10 05:48:40 UTC 
The following symbols were added to the kABI:

bus_register_notifier
bus_unregister_notifier
usb_free_urb
usb_get_urb
usb_register_driver

This one was denied by engineering review:

vmalloc_to_pfn

We need to update the kabi-whitelists package prior to RHEL6.1 release with these updates. Thanks for reminding me - it will be post-beta at this stage.
