Hello Martin, As you maybe know some time ago I started working on simplifying task management function handling in the SCSI target core (see e.g. "[PATCH 00/34] SCSI target patches for kernel v4.11"; January 2017; https://www.spinics.net/lists/target-devel/msg14054.html). There were some patches in that series that rightfully raised Nic's eyebrows. Reviewing these patches myself made me realize that before TMF handling can be made synchronous that some unusual constructs in the SCSI target core have to be reworked first. Hence this patch series. The following tests have been run against this patch series for both the iSCSI and SRPT target drivers: - Run the libiscsi conformance tests. - Run fio ${dev} in one shell and while sg_reset -d ${dev}; do :; done from another shell. This is a good way to stress test TMF handling. - For the SRP target driver: run the srp-test software. Please consider this patch series for kernel v4.16. Thanks, Bart.
