Current autotrim causes short-lived txg through: 1. calling txg_wait_synced() in metaslab_enable() 2. calling txg_wait_open() with should_quiesce = true This patch addresses all the issues mentioned above. A new cv, vdev_autotrim_kick_cv is added to kick autotrim activity. It will be signaled once a txg is synced so that it does not change the original autotrim pace. Also because it is a cv, the wait is interruptible which speeds up the vdev_autotrim_stop_wait() call. Finally, combining big zfs_txg_timeout, txg_wait_open() also causes delay when exporting a pool.
