Purge directory entry cache

Is there a “common” way to purge the dir entries cache of a directory
outside of the file system driver ? Ex: in a file system filter or just a
system thread.

For ntfs, the directory entry cache is managed by Scb for $I30 stream. For
fat, it’s done by the corresponding stream FileObject of the Dcb.

Any one has an idea ?

TIA,

Matt
