D'oh! [or something stronger] I KNEW it was something stupid. I thought it strange that there were no reports of something this glaring. That's why I took so long investigating before I finally asked. I've used debugfs+mmtrace on x86_64 in the past and I've had the debugfs mount in my test systems' fstab for so long that I don't even think about it [obviously!]. I moved to a different test system a couple of months ago and apparently brought over an old fstab patch. Sorry for the noise [he says sheepishly].
