Currently the TTL on VL server and address lists isn't set in all circumstances and may be set to poor choices in others, since the TTL is derived from the SRV/AFSDB DNS record if and when available. Fix the TTL by limiting the range to a minimum and maximum from the current time. At some point these can be made into sysctl knobs. Further, use the TTL we obtained from the upcall to set the expiry on negative results too; in future a mechanism can be added to force reloading of such data.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
