Subject: borked sysfs system devices in 2.5.72
Date: 17 Jun 2003 15:12:09 -0700	[thread overview]
Message-ID: <1055887929.24118.6.camel@nighthawk> (raw)

The per-node numa meminfo files in 2.5.72 are broken, the only display
node0's information.  The devices are being properly registered:
Registering sys device 'node0':c0423844 id:0 kobj:c042384c
Registering sys device 'node1':c0423888 id:1 kobj:c0423890
Registering sys device 'node2':c04238cc id:2 kobj:c04238d4
Registering sys device 'node3':c0423910 id:3 kobj:c0423918

When I look at the 4 nodes files with:
"cat /sys/devices/system/node/*/meminfo", I printed out some
information:
subsys_attr_show(kobj: c042384c, attr: c033ea30, page: e76ba000)
subsys_attr_show(kobj: c0423890, attr: c033ea30, page: e76ba000)
subsys_attr_show(kobj: c04238d4, attr: c033ea30, page: e76ba000)
subsys_attr_show(kobj: c0423918, attr: c033ea30, page: e76ba000)

As you can see, the kobj is the one which belongs to the sys device, yet
you do a to_subsys() on it.  Why?
struct subsystem * s = to_subsys(kobj);

I'm getting a 0 as the node ID out of pure dumb luck.  Is the NUMA code
broken or is sysfs?
