Hi,
...guess this is a Linux-Filesystem specific question... Why not ask
also on linux-fsdevel linux-fsde...@vger.kernel.org?

Maybe you will find lsof helpful, e.g.

lsof, as fuser, are /proc-scanning tools. Scanning /proc to then grep
the output is inefficient, and also non-atomic. I think Harald was
looking for an operation that did not involve scanning.

Laurent is right. BTW, I was not suggesting lsof was efficient. I just trew it
into the discusssion because sometimes it helped me on my home router.

Hi Laurent !
Sounds strange that you need to perform some cleanup on contents that
will disappear after the unmount anyway ^^
:)
Cleanup means deleting some unwanted stuff, then packing contents of
temporary filesystem in an archive to store that away for later usage.
If required a new
Hi Grant !
How are you going to prevent a race condition?
1) you check to see if the filesystem is in use and find that it
isn't.
2) another process opens/creates a file in the filesystem.
3) you do your cleanup.
4) you do a umount and it fails.
You are absolutely right. This race
Hi Grant !
If you want something that's atomic, then I think 'umount' is your
only option. If it fails, the fielsystem was busy. If it succeeds,
then it wasn't busy and is now unmounted.
Sure, I previously did that umount check on physical patitions, but my
current problem was, that the
