Subject: [PATCH] bpf: fix order of args in call to bpf_map_kvcalloc
Date: Thu, 16 May 2024 12:54:11 +0530
Message-ID: <20240516072411.42016-1-sheharyaar48@gmail.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The original function call passed size of smap->bucket before the number of
buckets which raises the error 'calloc-transposed-args' on compilation.
