RHEL5 is still only 2.6.18 though (says wikipedia), so regardless of details of exactly which version this struct appeared in we still want to support compiling on a system which doesn't have it. (I'm planning to apply this patch to master for rc0; I'll fix up the commit message to quote a better version number.) thanks -- PMM
