Merge tag 'ceph-for-4.9-rc5' of git://github.com/ceph/ceph-client
Pull Ceph fixes from Ilya Dryomov:
"Ceph's ->read_iter() implementation is incompatible with the new
generic_file_splice_read() code that went into -rc1. Switch to the
less efficient default_file_splice_read() for now; the proper fix is
being held for 4.10.
We also have a fix for a 4.8 regression and a trival libceph fixup"
* tag 'ceph-for-4.9-rc5' of git://github.com/ceph/ceph-client:
libceph: initialize last_linger_id with a large integer
libceph: fix legacy layout decode with pool 0
ceph: use default file splice read callback
