using fentry/fexit and fmod_ret is very convenient to access module BPF capabilities, so be able to define kfuncs there is a must. Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> --- new in v4: - I think this is where I need to add my new kfuncs, though in the end I need to be able to change the incoming data, so maybe only fmod_ret is the one we need to be able to be RW. --- kernel/bpf/btf.c | 3 +++ 1 file changed, 3 insertions(+)
