The following patch series adds snic driver for Cisco SCSI HBA
Cisco has developed a new PCI HBA interface called sNIC, which stands for
SCSI NIC. This is a new storage feature supported on specialized network
adapter. The new PCI function provides a uniform host interface and abstracts
backend s

The following patch exposes statistics for the st driver via sysfs.
There is a need for companies with large numbers of tape drives
numbering in the tens of thousands to track the performance of those
tape drives (e.g. when a backup exceeds its window). The statistics
provided should allow the calc
