Hi Linus,
Please pull the following Ceph updates from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
A few groups of patches here. Alex has been hard at work improving the
RBD code, layout groundwork for understanding the new formats and doing
layering. Most of the infrastructure is now in place for the final bits
that will come with the next window.
There are a few changes to the data layout. Jim Schutt's patch fixes some
non-ideal CRUSH behavior, and a set of patches from me updates the client
to speak a newer version of the protocol and implement an improved hashing
strategy across storage nodes (when the server side supports it too).
A pair of patches from Sam Lang fix the atomicity of open+create
operations. Several patches from Yan, Zheng fix various mds/client issues
that turned up during multi-mds torture tests.
A final set of patches expose file layouts via virtual xattrs, and allow
the policies to be set on directories via xattrs as well (avoiding the
awkward ioctl interface and providing a consistent interface for both
kernel mount and ceph-fuse users).
Thanks!
sage
