Hello,
This is to replace
40ca9b2c9bbb libceph: enlarge max number of operations in OSD request
d0c2fddbf154 libceph: move r_reply_op_{len,result} into struct ceph_osd_req_op
7c6ad0dab79d libceph: allow reserving operations in OSD request
The current solution is clunky: for larger than usual requests, it does
two memory allocations instead of one and wastes 3 ops (~500 bytes) of
memory for each request. This series fixes both of those.
Thanks,
Ilya

libceph: rename ceph_osd_req_op::payload_len to indata_len
libceph: osdc->req_mempool should be backed by a slab pool
libceph: enable large, variable-sized OSD requests
