Subject: [PATCH 0/4] scsi: ufs-debugfs: Add UFS Exception Event reporting

Hi

Here are patches to add a tracepoint for UFS Exception Events and to allow
users to enable specific exception events without affecting the driver's
use of exception events.


Adrian Hunter (4):
      scsi: ufs: Add exception event tracepoint
      scsi: ufs: Add exception event definitions
      scsi: ufs-debugfs: Add user-defined exception_event_mask
      scsi: ufs-debugfs: Add user-defined exception event rate limiting
