Allow resize of specific pools via the --pool-minimum-adjust and
--pool-maximum-adjust commands. The first affects the number of static

Now that libhugetlbfs supports multiple huge page sizes, it would be nice to
have a way to discover the huge page sizes that are supported by the system.
This new call should adhere to the semantics established by precedent
implementations (see
http://docs.sun.
When calling gethugepagesizes in a 32 bit environment it is possible that
some page sizeds will not be representable in the result. Ensure we detect
and elide these.

We have a couple of outstanding anomolies in the hugectl interface.
Firstly it does not allow control over verbosity/debug. Second it does
not allow request of backing for shared memory segments. We also have a
false warning triggered in options parsing. This patch series is designed
to address
When we hit the end of the arguments we will get a valid -1 return
from getopts_long. We should suppress this to prevent confusion.
