Revert "vf/remap: return the amount of bytes actually deduplicated"
This reverts commit 4a57a8400075bc5287c5c877702c68aeae2a033d.
Dave Chinner reports:
"As I suspected would occur, this change causes test failures. e.g
generic/517 in fstests fails with:
generic/517 1s ... - output mismatch [..]
-deduped 131172/131172 bytes at offset 65536
+deduped 131072/131172 bytes at offset 65536"
can you please revert this commit for the 5.19 series to give us more
time to investigate and consider the impact of the the API change on
userspace applications before we commit to changing the API"
That changed return value seems to reflect reality, but with the fstest
change, let's revert for now.
