Subject: [patch 121/147] bitmap: unify find_bit operations
Date: Tue, 07 Sep 2021 19:59:42 -0700 [thread overview]
Message-ID: <20210908025942.Sxli7QSKt%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210907195226.14b1d22a07c085b22968b933@linux-foundation.org>
From: Yury Norov <yury.norov@gmail.com>
Subject: bitmap: unify find_bit operations
bitmap_for_each_{set,clear}_region() are similar to for_each_bit() macros
in include/linux/find.h, but interface and implementation of them are
different.
This patch adds for_each_bitrange() macros and drops unused
bitmap_*_region() API in sake of unification.
