Subject: [PATCH 2/4] bcache: use div_u64() in init_owner_info()
Date: Wed, 10 Feb 2021 21:56:55 +0800	[thread overview]
Message-ID: <20210210135657.35284-2-colyli@suse.de> (raw)
In-Reply-To: <20210210135657.35284-1-colyli@suse.de>

Kernel test robot reports the build-in u64/u32 in init_owner_info()
doesn't work for m68k arch, the explict div_u64() should be used.

This patch explicit uses div_u64() to do the u64/u32 division on
32bit m68k arch.
