  To: Theodore Ts'o; +Cc: Eric Biggers, Eryu Guan, Vivek Goyal, fstests

At this time there is only one xfstest that requires namespaces
support (overlay/020) and it requires user namespace support.
This test fails with default kvm-xfstests configs.

Recently, a regression with overlayfs was reported relating
to mount ns, so tests that require only mount ns may be needed too.

This change re-enables the kernel default namespace support for all
kernel configurations and enables user ns support for stable kernels
v3.18 and above, where user ns is considered stable and maintained.
