# 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
