Merge tag 'ceph-for-4.20-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "The highlights are: - a series that fixes some old memory allocation issues in libceph (myself). We no longer allocate memory in places where allocation failures cannot be handled and BUG when the allocation fails. - support for copy_file_range() syscall (Luis Henriques). If size and alignment conditions are met, it leverages RADOS copy-from operation. Otherwise, a local copy is performed. - a patch that reduces memory requirement of ceph_sync_read() from the size of the entire read to the size of one object (Zheng Yan). - fallocate() syscall is now restricted to FALLOC_FL_PUNCH_HOLE (Luis Henriques)" * tag 'ceph-for-4.20-rc1' of git://github.com/ceph/ceph-client: (25 commits) ceph: new mount option to disable usage of copy-from op ceph: support copy_file_range file operation libceph: support the RADOS copy-from operation ceph: add non-blocking parameter to ceph_try_get_caps() libceph: check reply num_data_items in setup_request_data() libceph: preallocate message data items libceph, rbd, ceph: move ceph_osdc_alloc_messages() calls libceph: introduce alloc_watch_request() libceph: assign cookies in linger_submit() libceph: enable fallback to ceph_msg_new() in ceph_msgpool_get() ceph: num_ops is off by one in ceph_aio_retry_work() libceph: no need to call osd_req_opcode_valid() in osd_req_encode_op() ceph: set timeout conditionally in __cap_delay_requeue libceph: don't consume a ref on pagelist in ceph_msg_data_add_pagelist() libceph: introduce ceph_pagelist_alloc() libceph: osd_req_op_cls_init() doesn't need to take opcode libceph: bump CEPH_MSG_MAX_DATA_LEN ceph: only allow punch hole mode in fallocate ceph: refactor ceph_sync_read() ceph: check if LOOKUPNAME request was aborted when filling trace ...
