Date: Mon, 4 Jul 2022 21:16:09 +0200 From: Christophe JAILLET <christophe.jaillet@...adoo.fr> To: Johannes Berg <johannes@...solutions.net>, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com> Cc: linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, Christophe JAILLET <christophe.jaillet@...adoo.fr>, linux-wireless@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH] wifi: mac80211: Use the bitmap API to allocate bitmaps Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic.
