Hi,
In debugging minifilter driver code I found that the routines for create, read, write etc are getting executed multiple no of times. Further study indicated that it is executing two times with Requestor mode of 0 and 1 . I am not getting why this is happening?
Thank you.
Read and write will do this for a cached I/O, since the original user
request will trigger a kernel request to fill the cache. For the case of
Create, you will find there are an amazing number of creates that happen.
You have to look at the parameters to understand this stuff.
