btrace: Add in -r support for btrace
Using Ubuntu, debugfs is mounted on /debug instead of /sys/kernel/debug. [Perhaps, we should put in blktrace a search through "common" areas where debug could be mounted, and or do a simple parsing of the output from a 'mount' command to /find/ the directory.] Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
