Is the linux kernel s list.h thread safe?
No, the list_head struct doesn t contain any lock, and the operations are by no means atomic.

Paul McKenney gives an introduction to RCU on the ever-helpful LWN, from which you can glean some tips on managing thread-safe updates to linked lists. Of course, your usage may be simple enough that spinlocks will suffice.
