Hi,
The two atomic helpers in u_atomic.h, p_atomic_set and p_atomic_read,
are just passthrough macros, without the atomic guarantees. Why?
I believe I saw some corruption because of this, where a 64-bit
write on a 32-bit platform may not be naturally atomic.
From what I can tell p_atomic only supports 32-bits atomics. atomics don't
imply barriers, so
the code is probably correct for 32-bits. There is no 64-bits support in that
code,
so I don't see how that would have protected a 64-bits write..
