Hi Bart, > This series of three patches fixes a crash in the block layer core > that I encountered while retesting the SRP tests in blktests. Please > consider these patches for kernel v4.19.

Can you elaborate a bit on why the existing code fails with dm in the mix? -- Martin K. Petersen Oracle Linux Engineering
