OpenZFS 8063 - verify that we do not attempt to access inactive txg
Authored by: Matthew Ahrens <[email protected]> Reviewed by: Serapheim Dimitropoulos <[email protected]> Reviewed by: Pavel Zakharov <[email protected]> Approved by: Robert Mustacchi <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Ported-by: George Melikov <[email protected]> A standard practice in ZFS is to keep track of "per-txg" state. Any of the 3 active TXG's (open, quiescing, syncing) can have different values for this state. We should assert that we do not attempt to modify other (inactive) TXG's. Porting Notes: - ASSERTV added to txg_sync_waiting() for unused variable.
