Subject: [GIT PULL] Ceph updates for 4.20-rc1

Hi Linus,

The following changes since commit 84df9525b0c27f3ebc2ebb1864fa62a97fdedb7d:

  Linux 4.19 (2018-10-22 07:37:37 +0100)

  ceph: new mount option to disable usage of copy-from op (2018-10-22 10:28:24 +0200)

----------------------------------------------------------------
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)
