Merge tag 'ceph-for-6.7-rc1' of https://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: - support for idmapped mounts in CephFS (Christian Brauner, Alexander Mikhalitsyn). The series was originally developed by Christian and later picked up and brought over the finish line by Alexander, who also contributed an enabler on the MDS side (separate owner_{u,g}id fields on the wire). The required exports for mnt_idmap_{get,put}() in VFS have been acked by Christian and received no objection from Christoph. - a churny change in CephFS logging to include cluster and client identifiers in log and debug messages (Xiubo Li). This would help in scenarios with dozens of CephFS mounts on the same node which are getting increasingly common, especially in the Kubernetes world. * tag 'ceph-for-6.7-rc1' of https://github.com/ceph/ceph-client: ceph: allow idmapped mounts ceph: allow idmapped atomic_open inode op ceph: allow idmapped set_acl inode op ceph: allow idmapped setattr inode op ceph: pass idmap to __ceph_setattr ceph: allow idmapped permission inode op ceph: allow idmapped getattr inode op ceph: pass an idmapping to mknod/symlink/mkdir ceph: add enable_unsafe_idmap module parameter ceph: handle idmapped mounts in create_request_message() ceph: stash idmapping in mdsc request fs: export mnt_idmap_get/mnt_idmap_put libceph, ceph: move mdsmap.h to fs/ceph ceph: print cluster fsid and client global_id in all debug logs ceph: rename _to_client() to _to_fs_client() ceph: pass the mdsc to several helpers libceph: add doutc and *_client debug macros support
