Subject: mds: inode_t now uses modern encoding
X-Git-Tag: v0.58~100^2~65
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=843a35219c7cb8f34838c4823bf10ab60d27ec62;p=ceph.git

mds: inode_t now uses modern encoding

And we move implementations and the dumper into mdstypes.cc (from
mdstypes.h and common/types.cc).
