-# The linetimes.stp script takes two arguments: where to find the function
-# and the function name. linetimes.stp will instrument each line in the
-# function. It will print out the number of times that the function is
-# called, a table with the average and maximum time each line takes,
-# and control flow information when the script exits.
-#
-# For example all the lines of the do_unlinkat function:
-#
-# stap linetimes.stp kernel do_unlinkat
