Not that hard, although it is a bit tricky because command names may
contain spaces, so something obvious like this does not work in the
general case:
fstat /chroot |awk '$4 == "root" { print $3 }'
But the following seems more reliable, assuming the mount points do not
contain spaces:
#!/bin/sh
# USER CMD PID FD MOUNT INUM MODE SZ|DV R/W NAME
# jilles zsh 57711 root / 2 drwxr-xr-x 1024 r /
D="$1"
fstat "$D" | sed -Ene 's#^.* +([[:digit:]]+) +root +/[^ ]* +[[:digit:]]+ +.......... +[[:digit:]]+ +(r|rw|w) +'"$D"'$#\1#p'
This would need some |xargs kill or similar.
