DESCRIPTION
     The set of functions described above will help to gather statistics of
     the mounted HAMMER file systems in the system.

     All the functions will take argument value to store the value for the
     sysctl requested, except for libhammer_btree_stats() and
     libhammer_io_stats() which will take structures to store groups of
     values.

RETURN VALUES
     Upon successful completion, the value 0 is returned; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.
