Thanks for the pointer. I will change in the next version.
The other issue the bot reported on this patch is real as well:ðŸ˜
walking path->dentry in a BPF LSM program drops PTR_TRUSTED.
I will add BTF_TYPE_SAFE_TRUSTED for path in next version

bot is correct.
Please see commit 94e948b7e684 ("bpf: annotate file argument as __nullable in
bpf_lsm_mmap_file")
and add to kernel/bpf/bpf_lsm_proto.c when args can be NULL.
That's how verifier knows.*2*2
