The following patch set removes some inefficiencies in the iser data path through simplification and reducing the amount of code, using less atomic operations, avoiding TX interrupts, moving to iscsi passthrough mode, etc. I did my best to build it as a sequence of patches and not as one big re-write, to ease with maintainance (e.g bisection) and tuning.
changes from V1: - patch #5: removed white spaces - patch #8: fixed/adapted the xmit error flow to libiscsi's passthrough mode - patch #8: got review from Mike Christie Basically, with Mike's review on the libiscsi related changes being in place, I am not posting the whole patch series to the open-iscsi mailing list but rather only this piece. Roland, I'd be happy to get this in for the 2.6.34 merge window which is coming quite soon. Or.
