All this machinery is there to try to understand when there an async writeback waiting to complete because the intent log callbacks are still outstanding, and force them with a timely zil_commit(). The next commit fixes this properly, so there's no need for all this extra housekeeping. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Alexander Motin <alexander.motin@TrueNAS.com> Signed-off-by: Rob Norris <rob.norris@klarasystems.com> Closes #17584
