I do not think anyone has backported 2.6.27 (as I do not see a
kernel_addons/backport/2.6.27 backport dir).  The fix is a simple 1
liner in pagemap.h consisting of:
#define __grab_cache_page	grab_cache_page

Since there is not a backport dir for this kernel, do we really want to
add support for it this late in the OFED 1.4.1 release?  I have not done
any NFSRDMA testing for this kernel.  So this could end up to be
something that could delay the 1.41. release further.

Thanks,
Jon
