Does FILE_OBJECT->FsContext always point to FSRTL_COMMON_FCB_HEADER. If not how can I know when it does not.
-htfv
Ya, VCB, DCB, and FCB all have a FSRTL_COMMON_FCB_HEADER as their first member . Cc manager expects that FsContext points to a FSRTL_COMMON…, and this is respected by all standard disk file systems. However, altough Im sure you know this, File objects can be used to represent other things than file system streams. For those, the above does not hold true.
Ciao, Dan

For filesystems which allow memory mapped files and use Cache Manager - yes.

It’s a mandatory requirement for any on disk file system which uses Cc
manager.
