Subject: Re: pull-request: bpf-next 2022-03-21 v2
Hi Alexei,
So after this is merged, would you have a plan to merge the tip tree
which has IBT to the bpf-next? Or should I wait for merging this series
or IBT(ENDBR) series in Linus tree?
If I add the no ENDBR annotation to the x86 rethook trampoline on this
bpf-next branch, it will cause a build error...
Thank you,
