Subject: soft read-only fs

Hi,
I was trying to come up with a project to do and I was wondering if anybody
had done work on a filesystem to support soft read only mounts. This is
something I had seen on our F5 Big-IP boxes. They are based on BSD/OS for
those who are intrested.
The soft read-only functionality checks to see if files are open for writing.
If there are none, the file system gets downgraded to read-only. When a file
opens up for writing, the file system is promoted to read-write.
It's probably not a necessity with the more journaling filesystems that get
working with Linux. I just wanted to make sure I wasn't about to reinvent
the wheel (or fs if you like :-)
Cheers,
Ryan
