<para>The &os; network stack now runs entirely free of the
Giant kernel lock, and relies solely on the kernel's
fine-grained locking primitives to manage parallelism. This
significantly improves the network stack's performance on
multi-processor systems; uni-processor systems could also
see performance gains.
ISDN4BSD, &man.ng.h4.4;, and netatm have been temporarily
disconnected from the build. These modules all require
the Giant kernel lock for their operation; disconnecting
them allows the removal of the NET_NEEDS_GIANT compatability
shim and allows the &os; network stack to run completely
without the Giant kernel lock. It is planned to convert
shim. It is planned to convert
these modules to fine-grained kernel locking and re-connect
them for &os; 7.1-RELEASE.</para>
