> biolatency I wanted to give a shot at `biolatency` but I hit a wall as this is not easy to replace the tracepoint by `kprobes`. Indeed, the three tracepoints...

Hi. I took a look to this contribution and I am not able to choose what would be the correct way to go with it. I think there are several...

Hi! Is it posible to get some information regarding this? Particularly some pointers to have better understanding on what should be done to implement this feature? Best regards and thank...

Hi. Thank you for the all precision. > Could we land the ELF/datasec infra first and only target LINUX_VERSION_CODE initially, since we have existing code to obtain this value? (Meaning,...

Thank you for the pointer. I think I will give a try to implement the whole `__kconfig` parsing. I just need to think more about the steps given by Lmb,...

You can probably resurrect [patchValues](https://github.com/cilium/ebpf/commit/1ff15d21014336f653b09fe3842977f01c5945d2#diff-5ed7da7003773d8e0a4dca00d4fc08fc5582695eefe22a400db15edfd5aab840L1285-L1338) for step 2.
