93a61d7e6f Fix REPORT TARGET PORTAL GROUPS parsing 
Other changes:
- Bring the scst_scsi_op_table[] header in sync with <scsi/scsi.h>
- Fix parsing of the REPORT IDENTIFYING INFORMATION command: it has a four-byte
  length field instead of a two-byte length field.
- Fix devkey for other MAINTENANCE IN commands.

eaec88ff94 mvsas_tgt: SATA hotplug fix 
Cleanup and prepare the FIS index before issuing the ATA command (during prep:
mvs_task_prep_ata). This is to overcome the drive detection issue where the
SATA drives fail to get detected during hotplug since the ATA module (libATA)
detects errors set in the FIS even though the SATA analyzer shows that the
IDENTIFY command was successful.

This patch was provided by Praveen Murali <pmurali@logicube.com>.

Compared to the original patch, the changelog entry has been reformatted,
two spelling errors in comments has been fixed and fixed a checkpatch
complaint has been fixed too.

fa608d886b Fix a 3.4 kernel compilation warning 
Since kernel 3.4 the two-argument form of kmap() is deprecated and
triggers a compiler warning. Hence invoke kmap() with a single argument
on kernel 3.4 and later.

1bcac49c68 scst pr: Use fdatasync() instead of fsync() 
Synchronizing the file contents is sufficient - it is not necessary
to synchronize metadata like atime and mtime after having saved
persistent reservation information.

A more clear explanation of what "datasync" means can be found here
http://linux.die.net/man/2/fdatasync:

<quote>
fdatasync() is similar to fsync(), but does not flush modified metadata
unless that metadata is needed in order to allow a subsequent data
retrieval to be correctly handled. For example, changes to st_atime or
st_mtime (respectively, time of last access and time of last
modification; see stat(2)) do not require flushing because they are not
necessary for a subsequent data read to be handled correctly. On the
other hand, a change to the file size (st_size, as made by say
ftruncate(2)), would require a metadata flush.

The aim of fdatasync() is to reduce disk activity for applications that
do not require all metadata to be synchronized with the disk.
