List current inotify watches (pathname, PID)

How do I get a list of: * Pathnames currently being watched by inotify, and * PID of the process watching I ask because I have found that [syncthing](https://syncthing.net/) 's inotify watches were preventing my disk from being unmounted. As can be seen below, nothing appears in lsof or fuser listings. I guessed well with syncthing... How do I remove the guesswork in future if a disk won't unmount due to inotify? --------- # umount /media/backup umount: /media/backup: target is busy. # lsof +f -- /media/backup/ # echo $? 1 # fuser -vmM /media/backup/ USER PID ACCESS COMMAND /media/backup: root kernel mount /media/backup # systemctl stop syncthing@ravi # umount /media/backup # echo $? 0
