00:33 <kerneltoast> fche, agentzh, this is unholy but it works: https://gist.github.com/kerneltoast/a237d217c4cc00597d4e00ed1e5946be

00:34 <kerneltoast> backwards compat to older kernels could be hairy

00:34 <kerneltoast> (to *really* old kernels)

00:35 <kerneltoast> that patch fixes the lockdep warnings and passes our lean testsuite

00:46 <kerneltoast> currently checking to see if it fixes the probe_lock soft lockup bug too

00:47 <agentzh> kerneltoast: newer kernels also work with this patch?

00:47 <agentzh> like 5.x kernels?

00:47 <kerneltoast> they should be fine, but i haven't tested it

00:47 <agentzh> got it.

00:47 <kerneltoast> i was looking at 5.8 and 2.6.32 headers while i wrote it

00:47 <kerneltoast> so it should compile

00:48 <kerneltoast> after all, it's not helpful if the patch needs something that doesn't exist anymore :P

00:51 <agentzh> aye

06:57 <kerneltoast> fche, if it means anything to you, i updated the code in that gist to make it more robust. also, i have just confirmed it does NOT fix the probe_lock soft lockup

13:19 <fche> kerneltoast, is add_timer_on safe enough to be called from there?

13:34 <fche> kerneltoast, yeah other than that, it looks plausible, please see how it runs on those kernels too
