When a fake request is allocated we release it immediately, so it's wrong to release it also on a completion error (isert_pdu_err).

At teardown the refcount is reduced to zero and we start releasing the connection. In established event We need to check conn is not in teardown flow by checking its ref count is not 0.

Overview ======== This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files. QLogic target driver ==================== QLogic target driver qla2x00t is the old driver, forked from qla2xxx several years ago. It is very stable, well tested and actively used in many production setups. The ultimate goal is to have the mainstream (git) QLogic target driver to be the main and the only QLogic target driver, but, unfortunately, this driver not yet reached level of quality and maturity of qla2x00t. We with QLogic are working toward it. You can find the latest version of the git driver in git://git.qlogic.com/scst-qla2xxx.git. It is maintained by QLogic, hence located in the QLogic's git. To integrate it into the SCST build tree you need: 1. Clone the QLogic git tree somewhere in your system. 2. Create in the SCST root, i.e. this directory, a subdirectory with name qla2x00t_git 3. Optional for the in-tree build: symlink drivers/scsi/qla2xxx subdirectory in the cloned git tree to the qla2x00t_git subdirectory Thats all. Now common and QLA specific root Makefile targets "magically" start working with the new driver. For detail instructions how to setup QLA target build environment see its README or HOWTO. Run either "make all" to build the SCST core and all target drivers with in-tree QLogic drivers, or the following command with standalone QLogic drivers: BUILD_2X_MODULE=y CONFIG_SCSI_QLA_FC=y CONFIG_SCSI_QLA2XXX_TARGET=y make all In presence of qla2x00t_git subdirectory you can still build the qla2x00t using qla_old* root Makefile targets.
