Re: [PATCH 0/3] sys_membarrier (x86, generic)

Hi Andrew,

Here is a repost of sys_membarrier, rebased on top of Linus commit
c4b5fd3fb2058b650447372472ad24e2a989f9f6 without any change since the
last v19 post other that proceeding to further testing. When merging
with other system calls, system call number conflicts should be quite
straightforward to handle, there is nothing special there.

Hi Mathieu,

        Great to see this go in!  One small note: it talks about
threads, but membarrier as currently implemented would cover any shared
memory.  If you plan to optimize in future, that might not be the case:
we'd want an address argument for those cases?

Cheers,
Rusty.
