Disable runtime power management during domain validation. Since a later patch removes RQF_PREEMPT, set RQF_PM for domain validation commands such that these are executed in the quiesced SCSI device state.
This and "05/77] scsi: ide: Do not set the RQF_PREEMPT flag for" do not fix anything AFAICT. They are in series with other patches in 5.10, so they may make sense there, but I don't think we need them in 4.19.
Agreed. Please either backport the entire series of 8 patches or do not backport any patch from that series. Selecting a subset of the patches of that series is dangerous. As an example, applying patch 8/8 without applying the prior patches from that series would break SCSI domain validation.

Thanks,
