From 2b8bf3d6c99318eae669e3098c490ba6b508fd37 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 9 Jul 2022 16:37:53 +0200 Subject: [PATCH] net/fq_impl: 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.
