this series migrates the qemu rbd driver from the old aio emulation to native coroutines and adds write zeroes support which is important for block operations.
To achive this we first bump the librbd requirement to the already outdated luminous release of ceph to get rid of some wrappers and ifdef'ry in the code. V1->V2: - this patch is now rebased on top of current master with Paolos upcoming fixes for the meson.build script included: - meson: accept either shared or static libraries if --disable-static - meson: honor --enable-rbd if cc.links test fails - Patch 1: adjusted to meson.build script - Patch 2: unchanged - Patch 3: new patch - Patch 4: do not implement empty detach_aio_context callback [Jason] - Patch 5: - fix aio completion cleanup in error case [Jason] - return error codes from librbd - Patch 6: - add support for thick provisioning [Jason] - do not set write zeroes alignment - Patch 7: new patch Peter Lieven (7): block/rbd: bump librbd requirement to luminous release block/rbd: store object_size in BDRVRBDState block/rbd: update s->image_size in qemu_rbd_getlength block/rbd: add bdrv_attach_aio_context block/rbd: migrate from aio to coroutines block/rbd: add write zeroes support block/rbd: drop qemu_rbd_refresh_limits block/rbd.c | 418 +++++++++++++++++----------------------------------- meson.build | 13 +- 2 files changed, 142 insertions(+), 289 deletions(-) -- 2.17.1
