The VM didn't know about that, so we have a PageDirty page which has clean buffers. We rely upon the VFS writeback code to "discover" that this dirty page has clean buffers: the VFS will attempt to write the dirty page and will end up marking the page clean without performing any IO. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
