Josh Durgin 787f31330e rbd: add discard support ... Change the write flag to an operation type in RBDAIOCB, and make the buffer optional since discard doesn't use it. Discard is first included in librbd 0.1.2 (which is in Ceph 0.46). If librbd is too old, leave out qemu_rbd_aio_discard entirely, so the old behavior is preserved.
