dyson 96/12/14 09:54:21 Modified: sys/vm vm_extern.h vm_fault.c vm_map.c vm_map.h vm_mmap.c Log: Implement closer-to POSIX mlock semantics. The major difference is that we do allow mlock to span unallocated regions (of course, not mlocking them.) We also allow mlocking of RO regions (which the old code couldn't.) The restriction there is that once a RO region is wired (mlocked), it cannot be debugged (or EVER written to.) Under normal usage, the new mlock code will be a significant improvement over our old stuff.
