This patch changes the interface to dm-io, so that\nit reports two error bitmaps - error_bits and unsup_bits. The unsup_bit\nbitmap tracks BLK_STS_NOTSUPP or BLK_STS_INVAL errors, the error_bits\nbitmap tracks all the other errors.\n\ndm-raid1 is changed so that it won't fail a leg if it receives an error\nin the unsup_bits bitmap.\n\nThis patch (with 62dc37a819a5) fixes misbehavior if the user uses\nunaligned bio vectors on dm-raid1."
