Subject: [PATCH v2] bpf: Drop imprecise log message
Date: Tue, 23 Feb 2021 13:04:16 +0400	[thread overview]
Message-ID: <20210223090416.333943-1-me@ubique.spb.ru> (raw)
In-Reply-To: <20210222193111.3koc5bo3czetwltx@kafai-mbp.dhcp.thefacebook.com>

Now it is possible for global function to have a pointer argument that
points to something different than struct. Drop the irrelevant log
message and keep the logic same.

Fixes: e5069b9c23b3 ("bpf: Support pointers in global func args")
