Silva" , linux-hardening@vger.kernel.org Subject: [PATCH][next] nfsd: Replace one-element array with flexible-array member Message-ID: MIME-Version: 1.0 Content-Disposition: inline Precedence: bulk List-ID: X-Mailing-List: linux-hardening@vger.kernel.org One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace a one-element array with a flexible-arrayº member in struct vbi_anc_data and refactor the rest of the code, accordingly. This results in no differences in binary output.
