  | commit v6.19-rc1-1-g0f5bb0cfb0b40
  | Author: David Laight <david.laight.linux@gmail.com>
  | Date:   Wed Nov 19 22:41:26 2025 +0000

  |     fs: use min() or umin() instead of min_t()
  |     
  |     min_t(unsigned int, a, b) casts an 'unsigned long' to 'unsigned int'.
  |     Use min(a, b) instead as it promotes any 'unsigned int' to 'unsigned long'
  |     and so cannot discard significant bits.
  | ... 33 lines of the commit log omitted.
