It would be nice to have some short description for the operations and the types. Something what we can use in --help output. register, reserve, release, preempt, preempt-abort, and clear write-exclusive, exclusive-access, write-exclusive-reg-only, exclusive-access-reg-only, write-exclusive-all-regs, and exclusive-access-all-regs I'm not sure if for example "preempt" or "write-exclusive-reg-only" is obvious enough for end-users. The next question, what about to rename --operation to --command? The man-page describes blkpr as "run persistent reservations command on a device".
