[15:24] <ret2libc> hi! was the CONFIG_DYNAMIC_DEBUG always on in ubuntu kernels? I'm compiling a very simple HelloWorld module and I don't remember having to deal with /sys/kernel/debug/dynamic_debug/control ever
[15:25] <TJ-> ret2libc: it's been on for some time; can't say exactly when though
[15:26] <ret2libc> TJ-: would say at least 2 years?
[15:26] <TJ-> Yes, I recall using it 
[15:30] <ret2libc> interesting... most probably i was using printk(KERN_DEBUG instead of pr_debug. Thanks
[15:38] <TJ-> according to my git repo, it was introduced to the common configs in ubuntu-saucy
[15:38] <TJ-> ubuntu-saucy:debian.master/config/config.common.ubuntu:CONFIG_DYNAMIC_DEBUG=y
[15:39] <ret2libc> wow... pretty old then! yeah it must be that i was using printk instead of pr_debug. That's why I didn't deal with dynamic_debug
[23:38] <ali1234> does the hwe-edge kernel have this patch? https://patchwork.kernel.org/patch/10009311/
[23:38] <ali1234> if so, it does not fix the deadlock :(
[23:38] <ali1234> if not, can it please have it?
[23:39] <ali1234> i guess since i am building dummy_hcd out of tree with dkms, i can just apply it myself
[23:42] <ali1234> hmm okay it does not have the patch
