| |
Hello!
This is a sneak preview of a series providing diagnostics to help track down problems that would result in excessive csd_unlock() latencies:
1. Add source and destination CPUs to __call_single_data. I freely admit that I found the union declaration a bit confusing!
2. Provide CSD lock timeout diagnostics.
Thanx, Paul
