I have a server with port 25 closed. I was to be able
to run a script every time someone tries to connect to
port 25, but from the outside the port remains closed.
I need the script that I'm going to run get the IP
address that tried to connect.

I've already done it myself. But I ended up doing it the other
way around -- making DEBUG_RODATA dependent on !KPROBES
because I figured KPROBES is more important than DEBUG_RODATA
and it is less confusing for the user this way.

Yes. It should depend on:

Btw, this one can be quite a big deal. Try connecting an iPod and syncing
8GB of data to it. Oops.

Subject: [patch] sched: fix next_interval determination in idle_balance()
Fix massive SMP imbalance on NUMA nodes observed on
This patch cleans up the softirq in hardirq change. The hard irq threads
pin themselves to one of the CPUs that the IRQ affinity is on.

that the thread is pinned on is no longer part of the IRQ affinity.
