When storage network is unstable ?-EIO?, write ?do_sync_write?data to the storage, it can trigger the panic in ocfs2_start_trans.ocfs2_start_trans -> ocfs2_abort ->panic? whether there is a better way to solve this problem? Just mark as a mistake instead of ocfs2_abort. Finally, any feedback about this process (positive or negative) would be greatly appreciated.
