# io_uring_cmd I/O engine for nvme-ns generic zoned character device

# NOTE:
# Regular writes against a zone should be limited to QD1, as the device can
# reorder the requests.

# As the passthrough path do not use an IO scheduler (such as mq-deadline),
# the queue depth should be limited to 1 to avoid zone invalid writes.
