--- Comment #2 from Theodore Tso (tytso@xxxxxxx) ---
Can you reproduce this?   

And you may also want to send a report to linux-mm@xxxxxxxxx, since although it
was tripped in ext4_set_page_dirty, the WARN_ON check which is it doing are
fundamentally page specific, so this may very well be an mm problem:


static int ext4_set_page_dirty(struct page *page)
{
        WARN_ON_ONCE(!PageLocked(page) && !PageDirty(page));
        WARN_ON_ONCE(!page_has_buffers(page));
        return __set_page_dirty_buffers(page);
}
