K 10 svn:author V 3 alc K 8 svn:date V 27 2003-11-10T01:37:40.000000Z K 7 svn:log V 420 - 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. END
