Why bother with tracefs_mount here in the first place? You have the superblock the operation is applied for - right in the arguments. Just make that set_gid(sb->s_root, opts->gid); and be done with that. Same place in tracefs_apply_options()... Incidentally, I'm not sure you need to keep ->i_gid assignment - set_gid() won't miss that inode, so...
