Subject: [GIT PULL] Ceph updates for 4.17-rc1
Hi Linus,
The following changes since commit 0adb32858b0bddf4ada5f364a84ed60b196dbcda:
Linux 4.16 (2018-04-01 14:20:27 -0700)
are available in the git repository at:

ceph: quota: report root dir quota usage in statfs (2018-04-02 11:17:53 +0200)
----------------------------------------------------------------
The big ticket items are:
- support for rbd "fancy" striping (myself). The striping feature bit
is now fully implemented, allowing mapping v2 images with non-default
striping patterns. This completes support for --image-format 2.
- CephFS quota support (Luis Henriques and Zheng Yan). This set is
based on the new SnapRealm code in the upcoming v13.y.z ("Mimic")
release. Quota handling will be rejected on older filesystems.
- memory usage improvements in CephFS (Chengguang Xu). Directory
specific bits have been split out of ceph_file_info and some effort
went into improving cap reservation code to avoid OOM crashes.
Also included a bunch of assorted fixes all over the place from
Chengguang and others.
----------------------------------------------------------------
Chengguang Xu (18):
ceph: add newline to end of debug message format
