[Ocfs2-devel] Patch for 2.6 support in configure

[John Villalovos <John.L.Villalovos@intel.com>]

This patch add support for using a 2.6.x kernel when running configure.

It requires the user to use "--enable-kernel-2_6" to enable it.  It also
creates an OCFS_KERNEL_2_6 Makefile variable that is put into
Config.make.in

I am working on using this information in the src/Makefile to add
support for 2.6
