[PATCH] Linux socket-specific keepalive settings

[Ed Boraas]

Hi,

Below (and attached) is a simple patch that we've found useful at our
site. It simply enables the setting of the three per-socket keepalive
options (available in Linux 2.4 and above) on systems that support them.

These three socket options would also need to be added to the list of
available options in the "socket options" section of smb.conf.5.
