Include syscall.Stat_t on unix to the unexported fileStat structure rather than accessing it though an interface. Additionally add a benchmark for Readdir (and Readdirnames). Tested on linux, freebsd, netbsd, openbsd darwin, solaris, does not touch windows stuff. Does not change the API, as discussed on golang-dev. E.g. on linux/amd64 with a directory of 65 files: benchmark old ns/op new ns/op delta BenchmarkReaddir-4 67774 66225 -2.29% benchmark old allocs new allocs delta BenchmarkReaddir-4 334 269 -19.46% benchmark old bytes new bytes delta BenchmarkReaddir-4 25208 24168 -4.13% Change-Id: I44ef72a04ad7055523a980f29aa11122040ae8fe Reviewed-on: https://go-review.googlesource.com/16423 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>
