[opensuse-factory] Enabling CONFIG_BPF_KPROBE_OVERRIDE in tumbleweed
Hi, lately I've been using this BPF feature to override the return value on some memory allocations. It's very powerful, FYI see bcc's inject tool[1]. Sadly it isn't enabled in tumbleweed nor trough the debug configuration. So I was wondering if anyone had an opinion/objects enabling it by default or at least in the debug configuration.

Accidentally, two days ago I enabled it in -debug flavors in master branch while updating it to 4.20-rc1 so that packages in Kernel:HEAD (http://download.opensuse.org/repositories/Kernel:/HEAD/standard/) should already have it. I'm just not sure why this config suddenly appeared among new ones when it has been available since 4.16-rc1. I'll have to think about it some more to see if it makes sense to enable the option also in -default. Adding Jiří Slabý whom you will need if you do not want to wait for two more months until 4.20 reaches Tumbleweed.

Just installed the KOTD-debug and it fine. That's good enough for me
