The patch titled
mbind: restrict nodes to the currently allowed cpuset
has been removed from the -mm tree. Its filename was
mbind-restrict-nodes-to-the-currently-allowed-cpuset.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: mbind: restrict nodes to the currently allowed cpuset
From: Christoph Lameter <clameter@xxxxxxx>
Currently one can specify an arbitrary node mask to mbind that includes
nodes not allowed. If that is done with an interleave policy then we will
go around all the nodes. Those outside of the currently allowed cpuset
will be redirected to the border nodes. Interleave will then create
imbalances at the borders of the cpuset.
This patch restricts the nodes to the currently allowed cpuset.
