A question about zfs recv

[unkownerror1]

zfs version 2.1.5 ,hdd disk, disk performance is poor. Run the zfs recv command and then the df command,df command will block long time.I found that when recv ends, the fs will be suspended and z_teardown_lock will be held. Due to poor disk performance and high io latency, txg sync time will be longer and z_teardown_lock hold time will be longer. The df command will also want to hold z_teardown_lock, so df command will block for a long time.sometimes block 10 min. Can i create new issue for this question about df command blocking for a long time
