Merge tag 'ceph-for-4.11-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "This time around we have: - support for rbd data-pool feature, which enables rbd images on erasure-coded pools (myself). CEPH_PG_MAX_SIZE has been bumped to allow erasure-coded profiles with k+m up to 32. - a patch for ceph_d_revalidate() performance regression introduced in 4.9, along with some cleanups in the area (Jeff Layton) - a set of fixes for unsafe ->d_parent accesses in CephFS (Jeff Layton) - buffered reads are now processed in rsize windows instead of rasize windows (Andreas Gerstmayr). The new default for rsize mount option is 64M. - ack vs commit distinction is gone, greatly simplifying ->fsync() and MOSDOpReply handling code (myself) ... also a few filesystem bug fixes from Zheng, a CRUSH sync up (CRUSH computations are still serialized though) and several minor fixes and cleanups all over" * tag 'ceph-for-4.11-rc1' of git://github.com/ceph/ceph-client: (52 commits) libceph, rbd, ceph: WRITE | ONDISK -> WRITE libceph: get rid of ack vs commit ceph: remove special ack vs commit behavior ceph: tidy some white space in get_nonsnap_parent() crush: fix dprintk compilation crush: do is_out test only if we do not collide ceph: remove req from unsafe list when unregistering it rbd: constify device_type structure rbd: kill obj_request->object_name and rbd_segment_name_cache rbd: store and use obj_request->object_no rbd: RBD_V{1,2}_DATA_FORMAT macros rbd: factor out __rbd_osd_req_create() rbd: set offset and length outside of rbd_obj_request_create() rbd: support for data-pool feature rbd: introduce rbd_init_layout() rbd: use rbd_obj_bytes() more rbd: remove now unused rbd_obj_request_wait() and helpers rbd: switch rbd_obj_method_sync() to ceph_osdc_call() libceph: pass reply buffer length through ceph_osdc_call() rbd: do away with obj_request in rbd_obj_read_sync() ...
