[PATCH v2 2/3] blk-mq-debugfs: Also show requests that have not yet been started

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When debugging e.g. the SCSI timeout handler it is important that
requests that have not yet been started or that already have
completed are also reported through debugfs.
