"вкусная" ошибка в Linux, повреждение данных fs в ядрах >= 2.6.529.12.06 17:37 Автор: leo <Леонид Юрьев> Статус: Elderman Отредактировано 29.12.06 17:47 Количество правок: 2
Now, the fact that it apparently happens for all of ext2, ext3 and reiserfs (but NOT apparently with "data=writeback"), makes me suspect that there is some common interaction, and that it's somehow BH-related (they all share much of the buffer head infrastructure). So it doesn't look like it's just a bug in one random filesystem, I think it's a bug in some buffer-head infrastructure/helper function.
So I don't think it's "core VM". I don't think it's the "page cache". I think we handle the dirty state correctly at that level.
It looks more like "buffer cache" or "filesystem" to me by now.
