[PATCH v1 0/2] exfat: update percent_in_use, remove runtime integer division

Posted by David Timber 2 weeks, 6 days ago

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.
