The patch titled
mm: kevent threads: use MPOL_DEFAULT
has been removed from the -mm tree. Its filename is
mm-kevent-threads-use-mpol_default.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: mm: kevent threads: use MPOL_DEFAULT
From: Christoph Lameter <clameter@xxxxxxx>
Switch the memory policy of the kevent threads to MPOL_DEFAULT while
leaving the kzalloc of the workqueue structure on interleave. This means
that all code executed in the context of the kevent thread is allocating
node local.
