How do I find out what process has a lock on a file in Linux?

Today I had the problem that I couldn't delete a folder because "it was busy".

How can I find out which application to blame for that or can I just delete it with brute force?

lslocks lists information about all the currently held file locks in a Linux system. (part of util-linux) this utility has support for json output, which is nice for scripts.

~$ sudo lslocks
COMMAND           PID   TYPE SIZE MODE  M START END PATH
cron              873  FLOCK   4B WRITE 0     0   0 /run/crond.pid
