-commit e9c4f51ad2b76ddbf90863c44085574197247ba3
-Author: Auke Kok <auke-jan.h.kok@intel.com>

-
-    trace: tracer for sys_open() - sreadahead
-    
-    This tracer monitors regular file open() syscalls. This is a fast
-    and low-overhead alternative to strace, and does not allow or
-    require to be attached to every process.
-    
-    Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com>
