Kerneltrap: Linux: Data Corruption Bug Fixed Jan 1, 2007, 21 :00 UTC (0 Talkback[s]) (9440 reads) (Other stories by Jeremy)
""Both filesystem and VM actually _think_ they do the right thing, because they simply have totally different expectations. The filesystem thinks that it should care about dirty buffers (that got marked dirty _after_ they were dirtied), while the filesystem thinks that it cares about dirty _pages_ (that got dirted at any time _before_ 'writepage()' was called). Neither is really 'wrong', per se, it's just that the two parts have different expectations, and the _combination_ just doesn't work."
