NVME_RESERVATION_NOTIFICATION_TYPES enumeration (nvme.h)

Contains values that indicate the type of reservation notification in a Reservation Notification log page. A Reservation Notification log page is created whenever an unmasked reservation notification occurs on a namespace associated with the controller.

Reservation notifications may be masked from generating a reservation log page on a per reservation notification type and per namespace ID basis through the Reservation Notification Mask (NVME_FEATURE_NVM_RESERVATION_NOTIFICATION_MASK) feature.

A host may use the Asynchronous Event Request command to be notified of the presence of one or more available Reservation Notification log pages.
