Subject: [PATCH v2 0/2] ceph: metrics for remote object copies

Hi!

Here's v2 of this patchset.  The differences from v1:

  * Instead of changing ceph_osdc_copy_from() in libceph.ko to return an
    osd request, move that function into the cephfs code instead.

Other than that, the 2nd patch is quite similar to the one from v1: it
effectively hooks the 'copyfrom' metrics infrastructure.

Luís Henriques (2):
  ceph: libceph: move ceph_osdc_copy_from() into cephfs code
  ceph: add a new metric to keep track of remote object copies
