BTW, I thought Hans was talking about places that can't sleep (because of some not schedule-aware lock) when he said "place that cannot call balance_dirty()".
You were correct. I think Stephen and I are missing in communicating here.
Fine, I was just looking at it from the VFS point of view, not the specific filesystem. In the worst case, a filesystem can always simply defer marking the buffer as dirty until after the locking window has passed, so there's obviously no fundamental problem with having a blocking mark_buffer_dirty. If we want a non-blocking version too, with the requirement that the filesystem then to a manual rebalance once it is safe to do so, that will work fine too. --Stephen -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
