I checked my notes and the reason I held them back was that I was waiting for a response from Broadcom wrt. the megaraid segment size limitation. However, given that mpt3sas was acked, I assume it's the same thing. I'm not so keen on how big the last batch of patches for the merge window is getting. But I queued your fixes up for 5.3. -- Martin K. Petersen Oracle Linux Engineering
