     29 /* rf_archs.h -- defines for which architectures you want to
     30  * include is some particular build of raidframe.  Unfortunately,
     31  * it's difficult to exclude declustering, P+Q, and distributed
     32  * sparing because the code is intermixed with RAID5 code.  This
     33  * should be fixed.
     34  *
     35  * this is really intended only for use in the kernel, where I
     36  * am worried about the size of the object module.  At user level and
     37  * in the simulator, I don't really care that much, so all the
     38  * architectures can be compiled together.  Note that by itself, turning
     39  * off these defines does not affect the size of the executable; you
     40  * have to edit the makefile for that.
     41  *
     42  * comment out any line below to eliminate that architecture.
     43  * the list below includes all the modules that can be compiled
     44  * out.
