Matthew Ahrens 1ff46825e2 Replace zf_rwlock with a mutex ... The rwlock implementation on linux does not perform as well as mutexes. We can realize a performance benefit by replacing the zf_rwlock with a mutex. Local microbenchmarks show ~50% improvement, and over NFS we see ~5% improvement on several of the ZFS Performance Tests cases, especially randwrite and seq_write.
