Hi Jan,
Sorry to make you confused. My patch description was little wrong.
I meant only the emergency read-only remount case, not the normal read-only
remount case. Android is currently using emergency ro remount for the device
shutdown procedure.
We can easily reproduce this problem, but we didn't make a TC for xfstest yet.
If we did that, I will let you know.
