IRP_SYNCHRONOUS_PAGING_IO lazy write!

Body Hello,

I want to write a file filter program under windows 2000, but I really
meet with a truble.
When I create a new directory or *.wav in the directory "c:\test" that is
protected from write and delete operation, the system would send lazy
write warning(IRP_MJ_WRITE — IRP_SYNCHRONOUS_PAGING_IO). What would I do
?

Thanks,
hongjun zhang
