when read error and can rewrite,where do we rewrite?
It can't be rewrited to the old block.
It should be rewrite to other place,where can we find the 'other place'?
In the source code,I don't find the place that should be rewrited to.

It's rewritten to the same block - it's up to the low-level device (the
disk) to attempt a write and transparently remap the block if the write
fails.
