SCSI misc on 20150622 

This is the usual grab bag of driver updates (lpfc, hpsa,
 megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates.
 There are also one new driver: the Cisco snic; the advansys driver has
 been rewritten to get rid of the warning about converting it to the
 DMA API, the tape statistics patch got in and finally, there's a
 resuffle of SCSI header files to separate more cleanly initiator from
 target mode (and better share the common definitions).

Description:
Shows the total amount of time spent waiting for all I/O

reads, writes, and other SCSI commands issued to the tape
drive. An example of other SCSI commands would be tape
movement such as a rewind when a rewind tape device is
closed. This item is measured in nanoseconds.
To determine the amount of time spent waiting for other I/O
to complete subtract read_ns and write_ns from this value.

@ -151,6 +151,65 @@ A link named 'tape' is made from the SCSI device directory to the class
directory corresponding to the mode 0 auto-rewind device (e.g., st0).
SYSFS AND STATISTICS FOR TAPE DEVICES
The st driver maintains statistics for tape drives inside the sysfs filesystem.
The following method can be used to locate the statistics that are
available (assuming that sysfs is mounted at /sys):
1. Use opendir(3) on the directory /sys/class/scsi_tape
2. Use readdir(3) to read the directory contents
3. Use regcomp(3)/regexec(3) to match directory entries to the extended
regular expression "^st[0-9]+$"
4. Access the statistics from the /sys/class/scsi_tape/<match>/stats
directory (where <match> is a directory entry from /sys/class/scsi_tape
that matched the extended regular expression)
The reason for using this approach is that all the character devices
pointing to the same tape drive use the same statistics. That means
that st0 would have the same statistics as nst0.
The directory contains the following statistics files:
1. in_flight - The number of I/Os currently outstanding to this device.
2. io_ns - The amount of time spent waiting (in nanoseconds) for all I/O
to complete (including read and write). This includes tape movement
commands such as seeking between file or set marks and implicit tape
movement such as when rewind on close tape devices are used.
3. other_cnt - The number of I/Os issued to the tape drive other than read or
write commands. The time taken to complete these commands uses the
following calculation io_ms-read_ms-write_ms.
4. read_byte_cnt - The number of bytes read from the tape drive.
5. read_cnt - The number of read requests issued to the tape drive.
6. read_ns - The amount of time (in nanoseconds) spent waiting for read
requests to complete.
7. write_byte_cnt - The number of bytes written to the tape drive.
8. write_cnt - The number of write requests issued to the tape drive.
9. write_ns - The amount of time (in nanoseconds) spent waiting for write
requests to complete.
10. resid_cnt - The number of times during a read or write we found
the residual amount to be non-zero. This should mean that a program
is issuing a read larger thean the block size on tape. For write
not all data made it to tape.
Note: The in_flight value is incremented when an I/O starts the I/O
itself is not added to the statistics until it completes.
The total of read_cnt, write_cnt, and other_cnt may not total to the same
value as iodone_cnt at the device level. The tape statistics only count
I/O issued via the st module.
When read the statistics may not be temporally consistent while I/O is in
progress. The individual values are read and written to atomically however
when reading them back via sysfs they may be in the process of being
updated when starting an I/O or when it is completed.
The value shown in in_flight is incremented before any statstics are
updated and decremented when an I/O completes after updating statistics.
The value of in_flight is 0 when there are no I/Os outstanding that are
issued by the st driver. Tape statistics do not take into account any
I/O performed via the sg device.
BSD AND SYS V SEMANTICS
The user can choose between these two behaviours of the tape driver by
