But that's not true. You need to write you own sysctl handler for it,
probably worth adding a generic atomic_t sysctl handler while you're
at it.
I checked linux-2.6.13-rc7 tree, and atomic_read() is just a wrapper to read
v->counter.
In the ancient times, yes, atomic_read() was different on some archs, but not
today.
