What happens about the logging?
Surely one would want the output from one probe to be output into the
log as a block, and not mix the output from multiple simultaneous probes.
Use single-line printks were possible, or mutex-protected multiline
blocks where you really can't do without multiple lines of printks that
really cannot be separated. (Don't perform time consuming functions
within those mutexes; that would defeat the multithreaded probing...)
To adjust printks is only the beginning of what is to be done to adapt
single-threaded bus probes to multithreaded ones. There may be hidden
assumptions that rely on single-threaded execution.
