Subject: [PATCH 10/16] include/linux: move for_each_bit() macros from bitops.h to find.h
Date: Fri, 1 Oct 2021 11:12:39 -0700 [thread overview]
Message-ID: <20211001181245.228419-11-yury.norov@gmail.com> (raw)
In-Reply-To: <20211001181245.228419-1-yury.norov@gmail.com>
for_each_bit() macros depend on find_bit() machinery, and so the
proper place for them is the find.h header.
