Hi,
I am still experimenting with the VM code.
During this exploration I stumbled into this code,
from kflushd in fs/buffer.c
flushed = flush_dirty_buffers(0);
if (free_shortage())
flushed += page_launder(GFP_BUFFER, 0);
a) GFP_BUFFER is __GFP_HIGH and __GFP_WAIT but not __GFP_IO
Trying to launder without washing powder???
Or is it somehow guaranteed that flushed buffers are from
the same pages?
Should a GFP_KFLUSHD be introduced - like GFP_KSWAPD ?
b) Where is no_of_inactive_dirty pages balanced against inactive_clean?
(I have to look some more at this - remove my own patches first...)
