- 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)
