b25cb2a7e5 scst: Fix MAINTENANCE IN parsing 
Although I do not know of any initiator that asks for the extended
parameter data format when submitting a REPORT TARGET PORT GROUPS
command, I think it's a good idea to support that data format (i.e.
three most significant bits of the second CDB byte are 001 instead
of 000). The attached patch should implement that. Additionally,
cmd->op_name is set to something more descriptive than
"MAINTENANCE IN" in that patch.

95bc9b68ff scst: Simplify REPORT TARGET PORT GROUPS implementation 
The value of the variable allocation_length is identical to the value of the
variable buf_len. Hence eliminate the former. Also, for MAINTENANCE(IN)
cdb_len is always equal to 12 so the test "cdb_len > 1" can be eliminated too.

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.

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.
