- CONFIG_INFINIBAND_IPOIB_DEBUG also enables the "ipoib_debugfs"
+ CONFIG_INFINIBAND_IPOIB_DEBUG also enables files in the debugfs
virtual filesystem. By mounting this filesystem, for example with
- mkdir -p /ipoib_debugfs
- mount -t ipoib_debugfs none /ipoib_debufs
+ mount -t debugfs none /sys/kernel/debug
- it is possible to get statistics about multicast groups from the

The performance impact of this option is negligible, so it
is safe to enable this option with debug_level set to 0 for normal
