Set the “fastIO is not possible” flag in the FCB, but note - FCB
belongs to the FSD, you must not do this in filters.

Some routines within NT Kernel call FastIoxxx routines regardless of
setting the “IsFastIoPossible” flag. I’ve seen failures in DFS on W2K
Server pre-sp3 (And maybe later) because I didn’t have a fast io dispatch
table defined or initialized. I couldn’t figure out which routines had to
be initialized in this table, so I made one for every possible fast IO
routine that could be called, and I return FALSE or STATUS_NOT_IMPLEMENTED
from each of my routines.

See FastFat to determine which of your fast IO routines should return a
boolean or a I/O status.

This is for a FSD. I don’t know what you must do for a Filter.
