Subject: [PATCH] md/raid1:Fix a logic bug in fix_sync_read_error(). 
If  d==read_disk && success == 1 and then break, so d =
 read_disk. When exec this judgement: >>start = d; >>/*
 write it back and re-read */ >>while (d !=
 r1_bio->read_disk) { Because d == read_disk,so write and
 re-add did not exec.
