Subject: [PATCH 0/2] md: widen size/count types for large arrays
Date: Fri, 10 Jul 2026 06:23:27 -0700	[thread overview]
Message-ID: <20260710132329.7273-1-nishidafmly@gmail.com> (raw)

Two small type-widening fixes for large arrays.  Neither changes
behaviour or memory use on any current configuration.

  1/2 changes chunk_sectors and the stripe-cache count fields to unsigned
      int, matching how they are used and avoiding implicit sign
      extension in the cache shrinker's subtraction.

  2/2 widens the badblocks sector parameters from int to sector_t so the
      helpers do not narrow a sector_t argument on very large devices.

These are independent of the other md/raid5 patches I'm sending and can
be applied on their own.
