Subject: [PATCH v7 14/16] bcache: use div_u64() in init_owner_info()
Date: Sat, 10 Apr 2021 00:43:41 +0800	[thread overview]
Message-ID: <20210409164343.56828-15-colyli@suse.de> (raw)
In-Reply-To: <20210409164343.56828-1-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.
