(Whoops, there were only two patches, not three.) Update most of "include/linux/ceph/ceph_fs.h" to match its user space counterpart in "src/include/ceph_fs.h" in the ceph tree. Everything that has changed is either: - added definitions (therefore no real effect on existing code) - deleting unused symbols - added or revised comments There were some differences between the struct definitions for ceph_mon_subscribe_item and the open field of ceph_mds_request_args; those differences remain.
