While retaining the actual filtering according to trace level, the following commits started to write such filtered records with a hardcoded record level of 1 instead of the actual record level: commit 250a1352b95e1db3216e5c5d4f4365bea5122f4a ("[SCSI] zfcp: Redesign of the debug tracing for SCSI records.") commit a54ca0f62f953898b05549391ac2a8a4dad6482b ("[SCSI] zfcp: Redesign of the debug tracing for HBA records.") Now we can distinguish written records again for offline level filtering. Signed-off-by: Steffen Maier Fixes: 250a1352b95e ("[SCSI] zfcp: Redesign of the debug tracing for SCSI records.")
