Don Brady 975a13259b Add support for parallel pool exports ... Changed spa_export_common() such that it no longer holds the spa_namespace_lock for the entire duration and instead sets spa_export_thread to indicate an import is in progress on the spa. This allows for an export to a diffent pool to proceed in parallel while an export is still processing potentially long operations like spa_unload_log_sm_flush_all(). Calls like spa_lookup() and spa_vdev_enter() that rely on the spa_namespace_lock to serialize them against a concurrent export, now wait for any in-progress export thread to complete before proceeding. The 'zpool import -a' sub-command also provides multi-threaded support, using a thread pool to submit the exports in parallel. Sponsored-By: Klara Inc. Sponsored-by: Wasabi Technology, Inc.
