These patches are to add the printout of the request tag in Block/SCSI trace events when tracing one request or command, this is very useful for tracing the task running status in the storage device which supports multiple command queue.
As for the first patch " Add tag in SCSI trace events", copied from Rajat Jain . I am just re-sending here. https://patchwork.kernel.org/patch/6399661/ -- Resend since patches need to go through the block and SCSI subsystem, and need related maintainer's confirmation.
