From a4703e3184320d6e15e2bc81d2ccf1c8c883f9d1 Mon Sep 17 00:00:00 2001 From: Kumar Kartikeya Dwivedi Date: Thu, 21 Jul 2022 15:42:35 +0200 Subject: bpf: Switch to new kfunc flags infrastructure Instead of populating multiple sets to indicate some attribute and then researching the same BTF ID in them, prepare a single unified BTF set which indicates whether a kfunc is allowed to be called, and also its attributes if any at the same time. Now, only one call is needed to perform the lookup for both kfunc availability and its attributes.
