Ah, sorry. It was a bit whitespace damages on my end. This did really fix the megasas_raid boot hang here. Since 103fbf8e4020 ("scsi: megaraid_sas: Added support for shared host tagset for cpuhotplug") is now in the mainline, it probably makes sense to merge this patchset for v5.10 as well to avoid breakage.
