This allows profiling of a User-Mode Linux kernel with the gprof

utility.

say Y. If you're unsure, say N.

Track the maximum kernel stack usage - this will look at each
|
|
kernel stack at process exit and log it if it's the deepest
|
|
stack seen so far.
|
|
|
|
This option will slow down process creation and destruction somewhat.
