Can you do svn info in the userspace/management/osm directory ?

As Fab indicated, there are a number of places where the SM/SA is
needed:
1. SA PathRecords (used when a path to a new IP end node is needed or an
existing one timesout)
2. SA MCMemberRecord joins, queries, and leaves (used when an interface
is up'ed, down'ed, etc.)

Is this on an existing TCP session ? Is it OpenIB IPoIB clients at each
end ? What svn version is being used for this ?
