Memory Leak in Ntfs.sys

The driver Ntfs.sys was not releasing memory acquired on a mount request on a dismount request. The memory leak is small, so the problem will usually show up after a period of days. Poolmon can be used to check this problem. Look for FSrtl tag taking up a lot of the pageable memory. Performance Monitor can also be used to monitor pageable memory use.
