This set aims to reduce the long delay in applications reacting to ublk
server exit in the case of a "fully saturated" queue, i.e. one for which
all I/Os are outstanding to the ublk server. The first few patches fix
some minor issues in the ublk selftests, and the last patch contains the
main work and a test to validate it.
