Subject: [PATCH v3 bpf-next 3/6] tools/bpftool: Add BTF_KIND_FLOAT support
Date: Sat, 20 Feb 2021 04:49:56 +0100	[thread overview]
Message-ID: <20210220034959.27006-4-iii@linux.ibm.com> (raw)
In-Reply-To: <20210220034959.27006-1-iii@linux.ibm.com>

Only dumping support needs to be adjusted, the code structure follows
that of BTF_KIND_INT.

Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com>
