The prepare_to_wait_exclusive_head() function was modified in
commit d8894cbd11 ("scst.h: Refactor wait_event_locked() to enhance
usability and clarity"). It now returns an error if the current
interruptible thread has pending signals.
This patch introduces the scst_wait_for_cmd() helper function for the
scst_cmd_thread(). This new function handles the return value of the
prepare_to_wait_exclusive_head() appropriately.
This patch fixes the following Coverity complaint:
CID 321410 (#1 of 1): Unchecked return value (CHECKED_RETURN)
check_return: Calling prepare_to_wait_exclusive_head without
checking return value.
Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
QLogic target driver
Two QLogic target drivers are included in the SCST project.
The default driver is located in qla2x00t-32gbit directory and it supports up to 32 Gb/s FC. It is the newer one.
May anyone wish to switch back to the older driver that only supported up to
16 Gb/s adapters, it is located in qla2x00t directory. To make use of the
older driver build scst with environment variable QLA_32GBIT=no set.
