2021-06-15scsi: storvsc: Correctly handle multiple flags in srb_statusMichael Kelley1-28/+33
Hyper-V is observed to sometimes set multiple flags in the srb_status, such as ABORTED and ERROR. Current code in storvsc_handle_error() handles only a single flag being set, and does nothing when multiple flags are set. Fix this by changing the case statement into a series of "if" statements testing individual flags. The functionality for handling each flag is unchanged.

2021-06-15scsi: storvsc: Update error loggingMichael Kelley1-9/+10
When an I/O error is reported by the underlying Hyper-V host, current code provides details only when the logging level is set to WARN, making it more difficult to diagnose problems in live customer situations. Fix this by reporting details at ERROR level, which is the default. Also add more information, including the Hyper-V error code, and the tag # so that the message can be matched with messages at the SCSI and blk-mq levels. Also, sense information logging is inconsistent and duplicative. The existence of sense info is first logged at WARN level, and then full sense info is logged at ERROR level. Fix this by removing the logging of the existence of sense info, and change the logging of full sense info to WARN level in favor of letting the generic SCSI layer handle such logging. With the change to WARN level, it's no longer necessary to filter out as noise any NOT READY sense info generated by the virtual DVD device.
