The patch titled mm: add numa node symlink for cpu devices in sysfs has been removed from the -mm tree. Its filename was mm-add-numa-node-symlink-for-cpu-devices-in-sysfs.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mm: add numa node symlink for cpu devices in sysfs From: Alex Chiang <achiang@xxxxxx> You can discover which CPUs belong to a NUMA node by examining /sys/devices/system/node/node#/ However, it's not convenient to go in the other direction, when looking at /sys/devices/system/cpu/cpu#/ Yes, you can muck about in sysfs, but adding these symlinks makes life a lot more convenient.
