Stefan Hajnoczi 3e2cb9ee76 block: add IOC_PR_READ_RESERVATION ioctl ... Add a Persistent Reservations ioctl to read the current reservation. This calls the pr_ops->read_reservation() function that was previously added in commit c787f1baa5 ("block: Add PR callouts for read keys and reservation") but was only used by the in-kernel SCSI target so far. The IOC_PR_READ_RESERVATION ioctl is necessary so that userspace applications that rely on Persistent Reservations ioctls have a way of inspecting the current state. Cluster managers and validation tests need this functionality.
