+dnl # The VFS .create, .mkdir and .mknod callbacks were updated to take a
+dnl # umode_t type rather than an int.  The expectation is that any backport
+dnl # would also change all three prototypes.  However, if it turns out that
+dnl # some distribution doesn't backport the whole thing this could be
+dnl # broken apart in to three seperate checks.
