I thought this feature don't have a big impact on embedded. At First, 7K is not important but as time goes by, it could be huge with very small size feature for server or desktop. So I wanted to add it with optionally. :) In future, embedded also have a big ram then we can remove optional config completely, I think. > -Andi > > -- > ak@linux.intel.com -- Speaking for myself only. > > -- > To unsubscribe, send a message with 'unsubscribe linux-mm' in > the body to majordomo@kvack.org.  For more info on Linux MM, > see: http://www.linux-mm.org/ . > Don't email: email@kvack.org > -- Kinds regards, Minchan Kim
