To archive this we first bump the librbd requirement to the already outdated luminous release of ceph to get rid of some wrappers and ifdef'ry in the code. Peter Lieven (7): block/rbd: bump librbd requirement to luminous release block/rbd: store object_size in BDRVRBDState block/rbd: use stored image_size in qemu_rbd_getlength block/rbd: add bdrv_{attach,detach}_aio_context block/rbd: migrate from aio to coroutines block/rbd: add write zeroes support block/rbd: change request alignment to 1 byte block/rbd.c | 421 +++++++++++++++++----------------------------------- configure | 7 +- 2 files changed, 139 insertions(+), 289 deletions(-)
