I'm implementing a minifilter driver and I need to flush and purge the cache of files that I monitor.
I saw that recently Microsoft added a new API FltFlushBuffers2() that does flush and can also purge the cache.
In the past I used the cache manager API's to do that, but they are not safe to use and cause my driver to hang from time to time.
FltFlushBuffers2() seems to be supported only from Windows build version 19041 which still can't be installed on all computers.
What alternatives I have if I need to flush and purge files that I monitor from within my minifilter?
