Function Documentation

static int fix_num_threads ( struct dedos_dfg * dfg )

static

Fixes the thread assignment within the DFG such that the pinned and unpinned threads are accurate.

Must be run, because during execution the only hint of pinned/unpinned is msu blocking mode. To be run after DFG is fully parsed.

Returns: 0 on success, -1 on error
