Christoh et al, We have revisited our decision of not merging mpt2sas and mpt3sas driver after my e-mail below and we concluded that it will be good if we merge the code of both the drivers for long term maintenance and future product inclusions. However we have decided to generate two separate binaries mpt2sas.ko and mpt3sas.ko with retaining existing ioctl interfaces, this is to maintain same application interfaces as on today and keep downward compatibility. We have started this work and planning to conclude this activity in three to four months and will submit the patches as soon as they are available for early upstream review. Requesting you all to ACK and unblock the current patches on our SAS3 drivers, so that we can take the latest code as baseline for our patches for the merge. Please let us know if you have any specific questions.

We are committed to provide bug fixes ( Only bug fixes and no new features) across both the SAS2 and SAS3 source trees. We prefer the SAS2 and SAS3 drivers to stay separate and the reason is; merging of the drivers is a time consuming and error prone task and with SAS2 products at the maintenance mode we are thinking it will be risky to do the merge for now. Going forward for our future products we will be providing a merged driver (with common source separated out and having multiple kernel modules compiled out of single source directory for each of our products) to avoid maintenance overhead. So please let us know whether the current patches can be ACKED if we provide the applicable bug fixes to SAS2 or you see any other issues?.

So a big NAK from me for any mpt3 patches that aren't urgen bug fixes before we finally got the two drivers merged. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
