   1 # io_uring_cmd I/O engine for nvme-ns generic zoned character device
   2 #
   3 # NOTE:
   4 # Regular writes against a zone should be limited to QD1, as the device can
   5 # reorder the requests.
   6 #
   7 # As the passthrough path do not use an IO scheduler (such as mq-deadline),
   8 # the queue depth should be limited to 1 to avoid zone invalid writes.
