Fix for regression for bug introduced in Beta6 none

Description Mike Christie 2008-12-05 22:14:55 UTC 
Description of problem:

We need to fix a issue with the terminate rport io function getting called at the same time as the scsi eh abort code, the terminate rport io function getting called after it has reset it port id, and also drivers like fnic needing to cleanup/restart IO after a rport relogin.

Seems like a lot, but it is just a couple small patches. One was sent by JamesS upstream already:
http://marc.info/?l=linux-scsi&m=122849753004520&w=2
the other parts are small changes to fnic and libfc.

It is looking like it was a firmware issue where local aborts were not getting completed by firmware correctly. Testing in progress...
Comment 5 Abhijeet Joglekar 2008-12-10 18:02:51 UTC 
The patch set for this should be out by end of day today.

Fix for regression for bug introduced in Beta6

This patch fixes a regression that was introduced while submitting patches for Beta6 last week. The change is minor, low risk, and only in the fnic module. 

This patch was tested on top of kernel 126 (http://people.redhat.com/dzickus/el5/126.el5/) which included all the patches submitted for fnic and libfc for Beta6.

Please include in Beta6.

Thanks
