From: "Eric W. Biederman" <[email protected]> - In fill_inode() transate uids and gids in the initial user namespace into kuids and kgids stored in inode->i_uid and inode->i_gid.
- In ceph_setattr() if they have changed convert inode->i_uid and inode->i_gid into initial user namespace uids and gids for transmission. Cc: Sage Weil <[email protected]> Signed-off-by: "Eric W.
