From 7c63f26cb518f57aa5feaef7e0abe2697155df35 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Thu, 23 Dec 2021 22:33:42 +0100 Subject: [PATCH] lib: objagg: Use the bitmap API when applicable Use 'bitmap_zalloc()' to simplify code, improve the semantic and reduce some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency.
