serhei: glad to know the stack memory thing was not just me :)
<agentzh>
yeah i was aware of bpf_tail_call() but it is indeed quite limited.
<agentzh>
i did not know about bpf_iter.
<agentzh>
thanks for the pointer.
<agentzh>
and i found another interesting thing related to bpf_iter, which is task_vma.
<agentzh>
serhei: seems like there's very little docs regarding bpf_iter in google. do you happen to know some links? thanks!

Not sure. For any bpf functionality I hope for docs but don't expect them
<serhei>
bpf really really needs a NEWS file :-/
<fche>
git log?
<serhei>
that or lkml discussions, in essence
<serhei>
The point of a NEWS file is to pull 'changes users would be interested in' out of the mass of churn such as 'drop imprecise log message' and 'explicitly zero-extend R0 after 32-bit cmpxchg'
<fche>
kernelnewbies.org might [want to] have a column on that
<serhei>
bpf in particular, or the black art of how to follow lkml without information overload in general? :)
