Hi,
This small series improves error propagation on the transport component
to prevent an inconsistent state in the iscsi module. The bug that
motivated this patch results in a hanging iscsi connection that cannot
be used or removed by userspace, since the session is in an inconsistent
state.
That said, I tested it using the TCP iscsi transport (and forcing errors
on the triggered function), which doesn't require a particularly complex
container structure, so it is not the best test for finding corner cases
on the atomic attribute_container_device trigger version.
Please let me know what you think.
