Subject: [PATCH v1 0/2] exfat: update percent_in_use, remove runtime integer division
Date: Sat,  5 Sep 2026 17:10:41 +0000	[thread overview]
Message-ID: <20260905171043.922793-1-dxdt@dev.snart.me> (raw)

Changes from RFC v0:

  - use mul_u64_u32_div() for 32-bit arch without 64-bit integer
    division

mul_u64_u32_div() isn't so popular API, so I'm not sure it's available
on all arch.

I don't have a beefy machine to test my patches for all arch... If you'd
like to apply, I suggest waiting for the CI bots to finish testing. I
believe all submitted patches that apply to the master branch are tested
by the bots. I'll ping when the patches get a pass.
