Hi all,
auditing the perag code for the generic groups feature found an issue
where recovery of an extfree intent without a logged done entry will
fail when the log also contained the transaction that added the AG
to the extent is freed to because the file system geometry in the
superblock is only updated updated and the perag structures are only
created after log recovery has finished.
This version now also ensures the transactions using the new AGs
are not in the same CIL checkpoint as the growfs transaction.
