# Merge: a7726f6 9122eed

#     Merge tag 'ceph-for-4.17-rc1' of git://github.com/ceph/ceph-client
#     
#     Pull ceph updates from Ilya Dryomov:
#      "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"
