Complete OSPERT'07 modification: ospert_complete.patch (against Linux 2.6.20)
Note: The device driver as given in the patch is not safe for concurrent access from several user space clients because we did not want to introduce additional locks while tracing locking patterns. To avoid problems, either use only one user space client at a time or add a mutex and reference counting to the driver.
To comply with the Linux kernel license, the Linux patch is made available under the terms of the GNU General Public License (GPL).
A brief user guide can be found in the file HOWTO.markdown.
Please email Björn Brandenburg if you have any questions.
