Hi Folks,
What are the major and minor fault counts in the struct task_struct
meant to count?

On most Unix-like systems, a major fault is one that incurs I/O; a
minor fault (reclaim) is one that does not. It appears that on Linux
2.5.74, some faults counted as `major' do not sleep (e.g., ones that
hit the swap readahead).
