(Optional subsystem specific) Regarding existing test software: the SRP test software is a thorough test of the Linux block layer, SCSI core, dm-mpath driver, dm core, SRP initiator and target drivers and also of the asynchronous I/O subsystem. This test suite includes experimental support for the NVMeOF drivers. This test suite supports the rdma_rxe driver which means that an Ethernet adapter is sufficient to run these tests. Note: the focus of this test suite is the regular I/O path and device removal. This test suite neither replaces the libiscsi tests nor xfstests. See also https://github.com/bvanassche/srp-test.
