This bug was caught by LTP testcase fchmod06 on Blackfin platform. In the manpage of fchmod, "EPERM: The effective UID does not match the owner of the file, and the process is not privileged (Linux: it does not have the CAP_FOWNER capability)." But the ramfs nommu code missed the inode_change_ok POSIX UID/GID verification. This patch fixed this.
