Perhaps it's not the kernel thread itself that needs to be synchronized, but it is requirement from the design i.e data structure initialization must be in atomic operation? >and what is the preferred way of > stopping threads.

However, IIRC too, before you do that, make sure you do the proper cleanup e.g free the linked list you have created during kernel thread lifetime, stop and destroy workqueues you might created, release any locks you might grab etc. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
