Log:
Changes to msync(2)
- Return EBUSY if the region was wired by mlock(2) and MS_INVALIDATE
is specified to msync(2). This is required by the Open Group Base
Specifications Issue 6.
- vm_map_sync() doesn't return KERN_FAILURE. Thus, msync(2) can't
possibly return EIO.
- The second major loop in vm_map_sync() handles sub maps. Thus,
failing on sub maps in the first major loop isn't necessary.
