That said, even for the kernel, the only reason I noticed this problem was not because I've seen a lot of them per se, but because the pattern showed up in a very hot function. In fact, it's the same __rcu_read_unlock() function that I made the otherwise unrelated bugzilla entry for inlining: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49194 so it's quite possible that we don't have that many of them in the kernel either.
