Christophe Vu-Brugier 9bc6548f37 target: do not reject FUA CDBs when write cache is enabled but emulate_write_cache is 0 ... A check that rejects a CDB with FUA bit set if no write cache is emulated was added by the following commit: fde9f50 target: Add sanity checks for DPO/FUA bit usage The condition is as follows: if (!dev->dev_attrib.emulate_fua_write || !dev->dev_attrib.emulate_write_cache) However, this check is wrong if the backend device supports WCE but "emulate_write_cache" is disabled. This patch uses se_dev_check_wce() (previously named spc_check_dev_wce) to invoke transport->get_write_cache() if the device has a write cache or check the "emulate_write_cache" attribute otherwise.
