Red Hat Bugzilla – Bug 460189
block layer tagging needs several bug fixes from upstream
Last modified: 2008-10-21 16:40:39 EDT
Description of problem:
1. When block layer tagging is used by scsi-ml for host wide tagging we do not access the bqt counter under a lock so it is racey and can incorrectly report errors.
2. LLDs are setting the device queue depth to the host wide queue depth.
3. scsi-ml can queue a command with an invalid tag.
These are fixed upstream (#1 is being merged now).

I closing this because I thought we could port all the host based tag mapping for fcoe. It turns out all the drivers in RHEL5 did their own mapping, so the port was more invassive than I wanted to risk for just fcoe.
