/*
 * This confusing sequence of redefinitions of xdevmap allows lsof to size
 * its copy of the kernel's xdevmap[] table dynamically, based on the
 * kernel's nxdevmaps value.
 *
 * The net result is that there is a dummy struct XDEVMAP[1], defined in
 * dstore.c, that is never used.  The copy of the kernel's xdevmap[] table
 * is stored in the space malloc()'d in dproc.c and addressed by Xdevmap.
 * The last redefinition of xdevmap to Xdevmap causes the macros of
 * <sys/sysmacros.h> to use Xdevmap.
 *
 * All this is done: 1) to avoid having to allocate a large amount of fixed
 * space in advance to a copy of the kernel's xdevmap; and 2) to keep CC from
 * complaining about the absence of a "struct xdevmap xdevmap[]," matching
 * the "extern struct xdevmap xdevmap[]" declaration in <sys/sysmacros.h>,
 * while still allowing lsof to use the equivalent of a "struct xdevmap *"
 * construct instead, particularly with the kernel forms of the major() and
 * minor() macros.
