  • This commits adds a driver API and ioctls for controlling Persistent
    Reservations s/genericly/generically/ at the block layer. Persistent
    Reservations are supported by SCSI and NVMe and allow controlling who gets
    access to a device in a shared storage setup.

    Note that we add a pr_ops structure to struct block_device_operations
    instead of adding the members directly to avoid bloating all instances
    of devices that will never support Persistent Reservations.
