Description

In ll_lov_setstripe_ea_info() we forget to call ll_inode_size_unlock() in the out_req_free error path:

        ll_inode_size_lock(inode);
        oit.it_flags |= MDS_OPEN_BY_FID;
        rc = ll_intent_file_open(file, lum, lum_size, &oit);
        if (rc)
                GOTO(out_unlock, rc);
        rc = oit.d.lustre.it_status;
        if (rc < 0)
                GOTO(out_req_free, rc);

        ll_release_openhandle(file->f_dentry, &oit);

out_unlock:
        ll_inode_size_unlock(inode);
        ll_intent_release(&oit);
        ccc_inode_lsm_put(inode, lsm);
out:
        cl_lov_delay_create_clear(&file->f_flags);
        RETURN(rc);
out_req_free:
        ptlrpc_req_finished((struct ptlrpc_request *) oit.d.lustre.it_data);
        goto out;
}

This was found via code inspection. I didn't check if this path is reachable.
