Racer is a bunch of shell scripts that I wrote to try find race conditions in
JFS code. I have expanded them to be a general purpose race condition
tester. The scripts also found a couple bugs XFS and Reiserfs in 2.6.0-test1
but those have been fixed in 2.6.0-test4.
How it works is that the scripts randomly creates files 0 - 20, renames them,
deletes them, and links to them etc. If the filesystem survives for a couple
hours of beating that's considerred a pass.
The scripts are at:
http://kbugs.org/racer.tar.gz
Just use `./racer.sh` to run the scripts. Obviously, you won't want to run
the script on a production system.
When I wrote the scripts I tried to think about all the different types of
operations that you can do on a file but I probably missed a lot of them.
Probably someone more familiar with filesystem code could provide useful
feedback.
thanks,
Dan Carpenter
