do some additional testing before committing to long term support.
.. note: Please note that while it is possible to create and test erasure coded pools in this release, the pools will not be usable when you upgrade to v0.79 as the OSDMap encoding will subtlely change. Please do not populate your test pools with important data that can't be reloaded.
Upgrading
~~~~~~~~~
* CephFS recently added support for a new 'backtrace' attribute on
file data objects that is used for lookup by inode number (i.e., NFS
reexport and hard links), and will later be used by fsck repair.
This replaces the existing anchor table mechanism that is used for
hard link resolution. In order to completely phase that out, any
inode that has an outdated backtrace attribute will get updated when
the inode itself is modified. This will result in some extra workload
after a legacy CephFS file system is upgraded.
* The per-op return code in librados' ObjectWriteOperation interface
is now filled in.
* The librados cmpxattr operation now handles xattrs containing null bytes as
data rather than null-terminated strings.
