Verify consistency of attribute caching by varying the
acregmin NFS option.

The cached information is assumed to be valid for attrtimeo
which starts at acregmin.

Verify consistency of attribute caching by varying the
acregmax NFS option.

The cached information is assumed to be valid for attrtimeo which
starts at acregmin. An attribute revalidation to the server
that shows no attribute change doubles attrtimeo up to acregmax.
An attribute revalidation to the server that shows a change has
occurred resets it to acregmin.

Verify consistency of attribute caching by varying the
acdirmin NFS option.

The cached information is assumed to be valid for attrtimeo
which starts at acdirmin. Test that this is so.

Verify consistency of attribute caching by varying the
acdirmax NFS option.

The cached information is assumed to be valid for attrtimeo which
starts at acdirmin. An attribute revalidation to the server
that shows no attribute change doubles attrtimeo up to acdirmax.
An attribute revalidation to the server that shows a change has
occurred resets it to acdirmin.

Verify consistency of attribute caching by varying the
actimeo NFS option.

The cached information is assumed to be valid for attrtimeo
which starts and ends at actimeo.

Verify consistency of data caching by varying the
acregmin NFS option.

Verify consistency of data caching by varying the
acregmax NFS option.

The cached information is assumed to be valid for attrtimeo which
starts at acregmin. An attribute revalidation to the server
that shows no attribute change doubles attrtimeo up to acregmax.
An attribute revalidation to the server that shows a change has
occurred resets it to acregmin.

Verify consistency of data caching by varying the
acdirmin NFS option.

The cached information is assumed to be valid for attrtimeo
which starts at acdirmin. Test that this is so.

Verify consistency of data caching by varying the
acdirmax NFS option.

The cached information is assumed to be valid for attrtimeo which
starts at acdirmin. An attribute revalidation to the server
that shows no attribute change doubles attrtimeo up to acdirmax.
An attribute revalidation to the server that shows a change has
occurred resets it to acdirmin.

Verify consistency of data caching by varying the
actimeo NFS option.

The cached information is assumed to be valid for attrtimeo
which starts and ends at actimeo.

Run all tests: acregmin_attr, acregmax_attr, acdirmin_attr,
