Hi,

The first patch fixes the IO block-size used for submitting IO depending
on the throttle device max-sectors settings.

The second patch fixes the potential race condition between submitting IO
and setting PID of the background IO process to cgroup.procs.

Changes from v1:
    - Use $BASHPID to write the child sub-shell PID into cgroup.procs
      (Shinichiro Kawasaki)
    - Link to v1: https://lore.kernel.org/all/20241217131440.1980151-1-nilay@linux.ibm.com/

  throtl/002: calculate block-size based on device max-sectors setting
  throtl: fix the race between submitting IO and setting cgroup.procs
