(Certain system-calls are excluded at the moment out of caution - but i'll probably lift restrictions like sys_clone() use because sys_clone() can be done safely from a threadlet.) The code must be thread-safe, because the kernel can move execution to a new thread anytime and then it will execute in parallel with the main thread. There's no other requirement. Wrt. performance, one good model is to run request-alike functionality from a threadlet, to maximize parallelism. ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
