Regression from what? Ext3? Or some earlier kernel version?
What arguments are you giving to this test program of yours? It looks like it
does some number of reads and/or writes to the file, and then calls 10,000
msyncs with 50ms wait between each msync.
I'm not seeing any disk activity as a result. Was anything else reading or
writing to the file or to the file system at the same time?
