A deliberate choice was made to keep the mpt3sas separate from mpt2sas due to our 6 GIG product being truly mature with a noticeable ramping down of enhancements/releases. mpt3sas is at it's initial baseline with a healthy roadmap ahead. Architecturally there will be changes to the headers that will be only mpt3sas specific. Another reason to keep the source separate. The mpt3sas release schedules is on a faster cadence than mpt2sas so keeping the source aligned is problematic. >From a maintenance and test perspective having the source base separate >actually reduces the so called maintenance "hell". -- Regards, Nagalakshmi -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
