New Revision: 71859
URL: http://svn.reactos.org/svn/reactos?rev=71859&view=rev
Log:
[FLTMGR]
- Implement basic versions of FltRegisterFilter and FltUnregisterFilter
- Add layout of data for FLT_FILTER, FLT_INSTANCE, FLT_OBJECT and their accociated data
- Add basic rundown protection for the FLT_FILTER object
- Removed from the build for now because GCC doesn't like our fltkernel.h header
