44# The mess below is designed to pick the right set of objects to build and/or
45# lint.  We have three flavors:
46#
47#  1. proc and raw modules.  Only $(MODOBJS) are built.
48#  2. kvm modules for systems without kmdb.  Only $(MODOBJS) are built.
49#  3. kvm modules for systems with kmdb.  $(MODOBJS) and $(KMODOBJS) are built.
50#
51# Complicating matters, we'd like to make the distinction between 2 and 3 before
52# this Makefile is loaded.  By default, we'll assume that all kvm modules should

157# kmdb dmods must *not* stray from the module API.  To ensure that they don't,
158# we try to link them, at build time, against an object that exports the symbols
159# that they can legally use.  The link test object is, however, only built when
160# kmdb itself is built.  Requiring module developers to build kmdb first would
161# be painful, so by default, module-level builds don't do the link test (the
162# $(POUND_SIGN) assignment below takes care of that).  Builds of the entire
163# tree can, however, guarantee the construction of kmdb first, and as such can
164# override the setting of $(KMDB_LINKTEST_ENABLE).  This override causes the
165# link test to be run.
