From: Dave Chinner <dchinner@xxxxxxxxxx>
CHANGELOG:
o Add a description of the new opt_params structure.
o Fix indenting
o Add missing I_SPINODES to subopt_params
o Add a check for undefined minval/maxval into getnum_checked
o Drop "const" from struct opt_params - it would be removed in a later
patch anyway
Passing large number of parameters around to number conversion
functions is painful. Add a structure to encapsulate the constant
parameters that are passed, and convert getnum_checked to use it.
This is the first real step towards a table driven option parser.

/*
- * option tables for getsubopt calls
+ * Table for parsing mkfs parameters.
+ *
+ * Description of the structure members follows:
+ *
+ * name MANDATORY
+ * Name is a single char, e.g., for '-d file', name is 'd'.
+ *
+ * subopts MANDATORY
+ * Subopts is a list of strings naming suboptions. In the example above,
+ * it would contain "file". The last entry of this list has to be NULL.
+ *
+ * subopt_params MANDATORY
+ * This is a list of structs tied with subopts. For each entry in subopts,
+ * a coresponding entry has to be defined:
+ *
+ * subopt_params struct:
+ * index MANDATORY
+ * This number, starting from zero, denotes which item in subopt_params
+ * it is. The index has to be the same as is the order in subopts list,
+ * so we can access the right item both in subopt_param and subopts.
+ *
+ * minval, maxval OPTIONAL
+ * These options are used for automatic range check and they have to be
+ * always used together in pair. If you don't want to limit the max value,
+ * use something like UINT_MAX. If no value is given, then you either has
+ * to supply your own validation, or refuse any value in the 'case
+ * X_SOMETHING' block. If you forget to pass a min or max value here, but
+ * call a standard function for validating user's value, it will cause an
+ * error message notifying you about this issue.
+ *
+ * (Said in another way, you can't have minval and maxval both equal
+ * to zero. But if one value is different: minval=0 and maxval=1,
+ * then it is OK.)
