Ka Ho Ng 454bc887f2 uipc_shm: Implements fspacectl(2) support ... This implements fspacectl(2) support on shared memory objects. The semantic of SPACECTL_DEALLOC is equivalent to clearing the backing store and free the pages within the affected range. If the call succeeds, subsequent reads on the affected range return all zero. tests/sys/posixshm/posixshm_tests.c is expanded to include a fspacectl(2) functional test.
