// FTL statistics X-macro:
// this defines all of the stats currently known to SFTL in key name / serialized
// key number form. Stats users (parsers, savers, etc) define X_FTL_doStat to do
// something meaningful.
// The trivial case is the construction of s_statkey_e enum, which provides to C
// code an enumeration of the key name to the key number.
// A stat saver, for instance, compare a key from a blob to the key macro which
// is currently being expanded; if they match, put into a variable inside a struct
// that matches the name of the stat.
// A parser, on the other hand, would convert the symbol into a C string using
// the # preprocessor operator. It then has a string representation of the key
// name that it can print or add to internal data structures for future use.
//
// Let's dissect the enum creation:
// #undef X_FTL_doStat
// -- this undefines the X macro, in case it was previously defined
// #define X_FTL_doStat(_part, _val) S_STATKEY_ ## _part = (_val),
// -- Each time X_FTL_doStat is invoked below, it will take the token, paste
// -- S_STATKEY_ in front, and assign it the value. For instance, this:
// -- X_FTL_doStat(lbas_read, 1)
// -- becomes:
// -- S_STATKEY_ ## lbas_read = (1),
// -- which is interpreted by the preprocessor to mean:
// -- S_STATKEY_lbas_read = (1),
// -- Thus, we've created an enumeration without repeating the origial content.
// typedef enum {
// FTL_doAllStats
// -- this invokes the X macro for all of the ones in the doAllStats list
// S_STATKEY_VFL = 255,
// S_STATKEY_FIL = 254,
// -- these are special cases
// } s_statkey_e;
// -- and we're done! We now have something that looks like:
// typedef enum {
// S_STATKEY_lbas_read = (1),
// S_STATKEY_lbas_written = (2),
// ...
// S_STATKEY_VFL = 255,
// S_STATKEY_VFL = 254,
// } s_statkey_e;
// The neat part is the knowledge of key name/key number is centralized;
// no repetition is required.
