 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)
