The patch titled
Subject: kernel/kthread.c:kthread_create_on_node(): clarify documentation
has been removed from the -mm tree. Its filename was
kernel-kthreadc-kthread_create_on_node-clarify-documentation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Subject: kernel/kthread.c:kthread_create_on_node(): clarify documentation
- Make it clear that the `node' arg refers to memory allocations only:
kthread_create_on_node() does not pin the new thread to that node's
CPUs.
- Encourage the use of NUMA_NO_NODE.
[nzimmer@xxxxxxx: use NUMA_NO_NODE in kthread_create() also]
