[PATCH] btrfs: scrub: replace max_t()/min_t() with clamp_t() in scrub_throttle_dev_io()

From: Thorsten Blum
Date: Mon Sep 01 2025 - 11:02:31 EST


Replace max_t() followed by min_t() with a single clamp_t(). Manually
casting 'bwlimit / (16 * 1024 * 1024)' to u32 is also redundant when
using max_t(u32,,) or clamp_t(u32,,) and can be removed.

No functional changes intended.
