New Revision: 226824
URL: http://svn.freebsd.org/changeset/base/226824
Log:
contigmalloc(9) and contigfree(9) are now implemented in terms of other
more general VM system interfaces. So, their implementation can now
reside in kern_malloc.c alongside the other functions that are declared
in malloc.h.
