Revision be4b499323bf7291b491c6df51baae62f45b8404 authored by Erez Shitrit on 25 June 2015, 14:13:22 UTC, committed by Doug Ledford on 14 July 2015, 17:20:09 UTC
Whenever ib_cm gets remove_one call, like when there is a hot-unplug event, the driver should mark itself as going_down and confirm that no new works are going to be queued for that device. so, the order of the actions are: 1. mark the going_down bit. 2. flush the wq. 3. [make sure no new works for that device.] 4. unregister mad agent. otherwise, works that are already queued can be scheduled after the mad agent was freed.

Numa policy hit/miss statistics
/sys/devices/system/node/node*/numastat
All units are pages. Hugepages have separate counters.
numa_hit A process wanted to allocate memory from this node,
and succeeded.
numa_miss A process wanted to allocate memory from another node,
but ended up with memory from this node.
numa_foreign A process wanted to allocate on this node,
but ended up with memory from another one.
local_node A process ran on this node and got memory from it.
other_node A process ran on this node and got memory from another node.
interleave_hit Interleaving wanted to allocate from this node
and succeeded.
For easier reading you can use the numastat utility from the numactl package
(http://oss.sgi.com/projects/libnuma/). Note that it only works
well right now on machines with a small number of CPUs.
