Merge tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux
Pull module updates from Rusty Russell:
"The exciting thing here is the getting rid of stop_machine on module
removal. This is possible by using a simple atomic_t for the counter,
rather than our fancy per-cpu counter: it turns out that no one is
doing a module increment per net packet, so the slowdown should be in
the noise"
* tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:

module: Unlink module with RCU synchronizing instead of stop_machine
module: Wait for RCU synchronizing before releasing a module
