I don't think that's the case. Any kernel that supports relatime
supports the relatime mount option. It doesn't matter if the
filesystem defaults to it or not, MS_RELATIME is a valid mount
flag on all supported kernels.

I can't see where a current kernel would reject an attempt to mount
with the MS_RELATIME flag set, so if you're seeing that fail either
the mount program for your filesystem type is rejecting it or you've
got a very old kernel....

We require the supported OS for the test to be defined in every
test. it's pretty easy to check:

$ grep _supported_os tests/generic/010
_supported_os IRIX Linux
$

Try to run a test that isn't supported on Linux and you get:

xfs/095  [not run] not suitable for this OS: Linux

Cheers,

Dave.
