SUMMARY
You cannot unmount a directory using ansible.posix.mount with "state: unmounted" that has been mounted this way:
mount --rbind /dev /mnt/dev
mount --make-rslave /mnt/dev
However, performing "/usr/bin/umount -R /mnt/dev" works fine.
Setting "opts: -R" does not work either.

Linux raspberrypi 6.6.51+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.51-1+rpt3 (2024-10-08) aarch64 GNU/Linux
STEPS TO REPRODUCE
From the command line
mkdir -p /mnt
mount --rbind /sys /mnt/sys
mount --make-rslave /mnt/sys
- name: "Unmount /mnt/sys"
ansible.posix.mount:
path: "/mnt/sys"
opts: "-R"
state: unmountedEXPECTED RESULTS
It should successfully unmount the volume, recursively if necessary.
ACTUAL RESULTS
The mount fails to unmount, likely because of being mounted with --rbind and --make-rslave
