 This seems to be a problem on old Linux kernels (2.6.32 from what Travis
 log says) and tmpfs.
 
 Which Linux kernels do you hit successful builds on?
 Are they using tmpfs for /tmp?
 
 kosaki fixed it in
 Linux kernel commit 3d3727cdb07ff17ddc3c551ef8d03d37b60a0372
 "mm, fadvise: don't return -EINVAL when filesystem cannot implement fadvise()"
 (but old kernels will be around for many more years)

 I think we need to accept EINVAL in our tests, unless there is a way
 to force the test to run on a regular FS.

----------------------------------------
We tested ruby trunk every commits, but it failed randomly with linux container on travis.

build log is here: https://s3.amazonaws.com/archive.travis-ci.org/jobs/36822816/log.txt

It's caused by fadvice(2). it details is following:

```
# make test-all
TestIO#test_advise:
Errno::EINVAL: Invalid argument - /tmp/test_io20141001-24823-10d6utc (0, 0, willneed)

# make test-rubyspec
IO#advise supports the willneed advice type ERROR
Errno::EINVAL: Invalid argument -  (0, 0, willneed)
```

Is there workaround this?
