[OpenAFS] dynamic allocation of vcaches

[Steven Jenkins]

We have a patch (in RT 124344) for adding support to Linux for dynamic
allocation of vcaches rather than the current hard limit provided by
the -stat flag to afsd.  It currently does not have a command-line
argument to turn it on (i.e., if the patch is applied, you get dynamic
support), and I want to make sure the interface we provide is a
reasonable one.  I propose:

afsd -stat <N> -dynamic-vcaches

where N would be the initial value of the number of vcache entries but
that the cache manager could dynamically allocate as many as needed).

Any concerns with that feature and interface?


Thanks,
Steven Jenkins
