Shuhei Matsumoto 13ca6e52d3 bdev/nvme: Handle ANA transition (change or inaccessible state) correctly ... Previously, if a namespace is in ANA inaccessible state, I/O had been queued infinitely. Fix this issue according to the NVMe spec. Add a temporary poller anatt_timer and a flag ana_transition_timedout for each nvme_ns. Start anatt_timer if the nvme_ns enters ANA transition. If anatt_timer is expired, set ana_transition_timedout to true. Cancel anatt_timer or clear ana_transition_timedout if the nvme_ns exits ANA transition. nvme_io_path_become_available() returns false if ana_transition_timedout is true. Add unit test case to verify these addition.
