Interview with Kernel Hacker Robert Love

An anonymous reader writes: "An interview with the ever interesting Robert Love is at KernelTrap. Robert is author of the kernel preemption patch which has been merged into the 2.5 development kernel. In this interview, Robert discusses the status of Linux kernel preemption, talks about his recent involvement with the O(1) scheduler and explains his recent VM overcommit work. He also reflects upon Linus' use of Bitkeeper, the future of Linux, and the recent Kernel Summit in Ottawa. A Good Read."

Re:Can someone explain the preemptible kernel?

[Lionel Hutts]

It was discussed here. Briefly, it means that the kernel itself, just like user programs, can be preempted, preventing high latency.

The alternative, of course, is just to attack all sources of latency in the kernel, which should be both better and harder.
