| |
Hi,
I've come across a problem allocating chunks of CMA memory on a system under heavy disk access load which seems very similar to the situation described as the rationale for this patch:
https://lkml.org/lkml/2012/9/11/335
Basically buffer headers sitting on the LRU list preventing them from being dropped during page migration.
I've tried the patch and it seems to solve my problems, so I'm wondering if it is worth resubmitting. The discussion on the original thread seems to have faded out. Does anyone know if it was continued somewhere else?
Thank you, Damian -- Damian Hobson-Garcia IGEL Co.,Ltd http://www.igel.co.jp
