From: Filipe Manana <fdmanana@xxxxxxxx>
Hi Chris,
Please consider the following device replace related fixes for inclusion
in a future 4.7 release candidate kernel. These were all previously sent
to the mailing list and reviewed by Josef (and I recently rebased them
against your for-linus-4.7 branch). They mostly fix crashes, invalid
memory accesses and data/metadata loss (some extents, or entire block
groups, end up not being copied from the source device into the target
device).
Thanks.
