I'm looking at the kernel config right now. |
| 4 |
Is it dangerous to change some of the kernel config options? |
| 5 |
Are there specific options that the lustre patches depend on? |
| 6 |
For example, since I'll be running this on a box with interactive graphics, I'd like to |
| 7 |
change the Preemption Model to "Preemptible Kernel". |
