858d02e558 [PATCH] ib_srpt: Always set RSPVALID flag in task management replies 
The SRP spec requires not only to set the RSPVALID flag and the RSP_CODE
field if a task management function failed but also if it succeeded. This
patch avoids that the SRP initiator interprets task managment functions
that succeeded as failed.

6e31fd8306 Relax and cleanup HARDWARE ERROR sense usage 
HARDWARE ERROR sense is very strong considered be "internal failure", so
might lead to serios initiator side issues up to disconnect from device. In
many cases WRITE or READ ERROR sense can be used instead. All remaining
usages must be logged.

2093dd7561 Make it possible to forcibly close SRP and FC sessions via sysfs 
That patch contains the following changes:
* Move the code for creating a "close_sess" sysfs attribute from iscsi-scst to
  the SCST core such that it becomes available for other target drivers. This
  does not change the functionality of iscsi-scst.
* Add code in ib_srpt and qla2x00t to allow a session to be forcibly closed from
  user space.

369863f015 Allow install SCST in any location 
Currently the install location of SCST is pretty much hard coded into 
the Makefiles to be /usr/local.

I am custom building a system for ZFS & SCST and I want to install in 
/usr instead of /usr/local.

Currently I am doing a “find . -name Makefile -exec sed -i 's:/usr/local:/usr:g'
{} \;” to accommodate this.

This patch fixes it.

bd7c893f04 Multiple makefiles: autodetect SCST include directory 
It is cumbersome to change SCST_INC_DIR and SCST_DIR in each Makefile
before and after a release. Hence modify the Makefiles such that these
paths are detected automatically.
