Currently, tcmu does not get any response from userspace for device addition, removal and now reconfigure requests. This can result in partially created devices that initiators have access to and do not handle well. The first patch is just some cleanups to the reconfigure code. Patches 2 - 3, make the dev_index idr based, because tcmu needs a way for userspace to tell the kernel that it has executed a operation on a device. Patches 4 makes add, del and reconfig sync so we can get info back from userspace before return succes/failure to LIO. Patches 5 - 6 fix bugs in tcmu found during addition failure handling. Patches 7 - 9 convert the xcopy code to use the idr helpers to loop over devices. I have not tested patches 7 - 9. -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
