Bug Description
https:/
"In certain circumstances, "zfs send -i" (incremental send) can produce
a stream which will result in incorrect sparse file contents on the
target.
The problem manifests as regions of the received file that should be
sparse (and read a zero-filled) actually contain data from a file that
was deleted (and which happened to share this file's object ID)."
This bug causes data corruption, and has privacy/security implications. I think we need to get this fix into Xenial ASAP.
