When the preempt-kernel patch is > applied, all processes automatically benefit. The API is the same but you still need to recompile all your modules with the patched kernel. (It is a good idea to bump the exta version information in the Makefile for the same reason.) Old modules may not load correctly with a preemptive patched kernel. -- Kernelnewbies: Help each other learn about the Linux kernel.
