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