Review request for mesos, Deepak Goel and Gilbert Song.
Bugs: MESOS-9518
https://issues.apache.org/jira/browse/MESOS-9518
Repository: mesos
Description
-------
In recent versions of kernels, the device number of '/proc/<pid>/ns/net'
is different than that of '/proc'. It shows up as "nsfs" instead of
"proc" like the old kernels. For instance:
Newer kernel:
```
$ uname -nr
ubuntu-xenial 4.4.0-83-generic
$ stat -L -c %d /proc/self/ns/net
3
$ stat -L -c %d /proc
4
```
Older kernel:
```
$ uname -nr
core-dev 3.10.0-693.5.2.el7.x86_64
$ stat -L -c %d /proc/self/ns/net
3
$ stat -L -c %d /proc
3
```
As a result, we should compare the device number directly against the
namespace handle, instead of `/proc`.
