Hi, It looks like after the recent changes to nbd driver, on-the-fly resize has stopped working for rbd-nbd. Particularly this change [1] breaks how NBD_SET_SIZE is used for rbd-nbd on-the-fly resize [2].
Could this be fixed? [1] https://github.com/torvalds/linux/commit/639812a1ed9bf49ae2c026086fbf975339cd1eef [2] https://github.com/ceph/ceph/blob/483f14c/src/tools/rbd_nbd/rbd-nbd.cc#L488 -- Mykola Golub
