Subject: [PATCH v2 0/2] mul_u64_u64_div_u64: new implementation
Date: Tue, 2 Jul 2024 23:34:07 -0400 [thread overview]
Message-ID: <20240703033552.906852-1-nico@fluxnic.net> (raw)
This provides an implementation for mul_u64_u64_div_u64() that always
produces exact results.
Changes from v1 (https://lkml.org/lkml/2024/6/28/1130):
- Use the already available u128 type instead of "unsigned __int128".
- Add a test module.
