- The Open Group Base Specifications Issue 6 specifies that an munmap(2)
must return EINVAL if size is zero. Submitted by: tegge
- In order to avoid a race condition in multithreaded applications, the
check and removal operations by munmap(2) must be in the same critical
section. To accomodate this, vm_map_check_protection() is modified to
require its caller to obtain at least a read lock on the map.
