[PATCH v2 0/2] ceph: support cross-quota-tree renames

[Luis Henriques]

Hi!

The following patches will make the cephfs kernel client behave the same
way as the fuse client when doing renames across different quota realms.

Changes since v1:

- Dropped 'old == new' check in ceph_quota_check_rename() and added back
  optimization in ceph_rename(), to only check realms if old_dir and
  new_dir are different.

Luis Henriques (2):
  ceph: normalize 'delta' parameter usage in check_quota_exceeded
  ceph: allow rename operation under different quota realms
