  Log Message:
  -----------
  ZFS has built-in replication and backup functionality, which serializes a
filesystem for transport to another system, known as "ZFS send".  ZFS send
also supports incremental updates between a pair of snapshots.  When sending
an encrypted dataset, the dataset can either be left encrypted for
transit/receipt (raw mode), or decrypted.  During a decrypting (normal) send,
a bug in the code caused some metadata (key mappings) in the snapshots to be
decrypted in memory, but not properly released.  As a result, the key mappings
used for decryption were not freed from the in-memory table.
