Hi,
I deleted the original thread, so I can't reply there. Just a heads up on the spinlock inlining on sparc64. I decided to give your patches a shot, since one of my IO benchmarks here basically degenerates into a spinlock microbenchmark with > 50% time spent there (unlock part, according to perf). Some of that is surely caching effects, but still.
For this particular workload, I get a net improvement of about 3.5% with the inlined functions. Not bad.
