Update of /data/cvs/samba/source/locking
In directory samba:/tmp/cvs-serv25239/locking

Modified Files:
	brlock.c posix.c 
Log Message:
Fix for stacking locks in brlock and POSIX. Windows only allows a read lock
to overlay a write lock on the same fnum. When overlaying read locks onto
a write lock, the number of locks is counted, and the first unlock removes
the write lock and downgrades this to a read lock. Do the same when mapping
to POSIX.
