| |
Hi Linus,
There is no reason why bdflush should call page_launder().
Its pretty obvious that bdflush's job is to only write out _buffers_.
Under my tests this patch makes things faster.
Guess why? Because bdflush is writing out buffers when it should instead blocking inside try_to_free_pages().
Please apply.
