Subject: [PATCH 13/13] bcache: use div_u64() in init_owner_info()
Date: Wed, 14 Apr 2021 13:46:48 +0800 [thread overview]
Message-ID: <20210414054648.24098-14-colyli@suse.de> (raw)
In-Reply-To: <20210414054648.24098-1-colyli@suse.de>
Kernel test robot reports the built-in u64/u32 in init_owner_info()
doesn't work for m68k arch, the explicit div_u64() should be used.
This patch explicit uses div_u64() to do the u64/u32 division on
32bit m68k arch.
