(sorry for being offtpoic, but while experts are here...)
A "typical" implementation of atomic_add_unless() can return 0 immediately
after the first atomic_read() (before doing cmpxchg). In that case it doesn't
provide any barrier semantics. See include/asm-ia64/atomic.h as an example.We should either change the implementation, or fix the docs.

atomic_ops.txt has incorrect, misleading and insufficient information about
semantics of initializer, atomic_set, atomic_read and atomic_xchg.It also incorrectly implies that operations mentioned above are not actual
atomic operations.Included is most of the patch Document non-semantics of atomic_read() and
atomic_set() by Chris Snook, except the word "assignment".Signed-off-by: Matti Linnanvuori

Introduce an atomic_inc_not_zero operation. Make this a special case of
atomic_add_unless because lockless pagecache actually wants
atomic_inc_not_negativeone due to its offset refcount.Signed-off-by: Nick Piggin

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
