I am writing a software that requires to find out about a file's reference
count (i.e. the number of times it is being opened by processes at a
particular time). Stat() and fstat() are not the solution as they only tell you
about the number of hardlinks.

Is there a system call that I can use to get this file reference count
information? Do I have to modify the kernel and add a new system call? I would
rather not touch the kernel if I can help it such as by using a few system
calls (what are they, though?) to accomplish the task.

Please send me email (albert@ee.su.oz.au) if you can help.
A million thanks.
