Date: Fri, 3 May 2024 20:25:07 +0200 Message-ID: <20240503182957.1042122-4-bigeasy@linutronix.de> In-Reply-To: <20240503182957.1042122-1-bigeasy@linutronix.de> References: <20240503182957.1042122-1-bigeasy@linutronix.de> Precedence: bulk X-Mailing-List: netdev@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-Patchwork-Delegate: kuba@kernel.org The else condition within __netdev_alloc_frag_align() is an open coded __napi_alloc_frag_align(). Use __napi_alloc_frag_align() instead of open coding it. Move fragsz assignment before page_frag_alloc_align() invocation because __napi_alloc_frag_align() also contains this statement.
