When iscsi-scstd exits for some reason, release on character device ctr_name is called. The release function of this character device calls target_del_all(). In order to avoid a scenario where isert-scst is being removed at the same time as iscsi-scstd is closing ctr_name device, increment reference count in portal creation so that the module will not disappear before target_del_all() finishes using it. This scenario is only relevant for isert-scst, as iscsi-scst will have positive reference count at least untill target_del_all() finishes due to __fput() being called only after the release method of the character device has returned.

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.
