I know that if the read request of raid5 is handled by
chunk_aligned_read, there is no error handling in raid5. But, if this
read request is not aligned, that's say, raid5 need stripe_head to
deal with this request. I find in the code of 2.6.27 that there is no
error handling if this read request fail, I remember in older kernel,
some operations should be done such as compute_block. Am I right?
