-stable review patch. If anyone has any objections, please let us know.
------------------
From: NeilBrown <[email protected]>
When 'repair' finds a block that is different one the various
parts of the mirror. it is meant to write a chosen good version
to the others. However it currently writes out the original data
to each. The memcpy to make all the data the same is missing.
