I neglected the header file; attached is an additional patch to catch
it. Both of these patches should apply cleanly to head.

Hey guys,
This patch fixes a client data corruption issue on Linux 2.4
systems. We worked with Phil off-list and determined that the
kernel's mapped buffers are not staying pinned in memory as they
should be. We were able to verify that under heavy swapping the
pvfs2-client-core memory was being moved, invalidating the pointers.
This fix uses mlock to hold the two buffers in place, and we were
able to verify that it fixes the swapping issue. There are compile
time flags to ensure it is only added for Linux 2.4 systems.
Bart.
