This patch introduces functional tests for FTL bdev. The tests cover various I/O workflows and check data integrity. Several scripts have been added to test the FTL library: * generate_config.sh - prepares configuration scripts for specified device * restore.sh - tests restoring device's state from the SSD * fio.sh - runs tests based on fio and fio_plugin The tests are run from autotest.sh when the SPDK_TEST_BDEV_FTL flag is set.
