Just a couple of notes: - dmu_offset_next_sync=3D0 does appear to be a very reliable workaround, ju= st not technically perfect. Only one person has been able to trip it on an extreme= ly contrived test, as opposed to the default =3D1, which multiple people have = been able to reproduce consistently. - The incorrect dirty check in 12.4 (as in Illumos) is in dmu_object_wait_synced(). I have not explored this at all though; OpenZFS n= ever had this version and a lot has changed since. There may be other reasons wh= y it can't be tripped. Let me know if there's anything I can assist with. Rob. --=20 You are receiving this mail because: You are the assignee for the bug.=
