Right now, my FS filter driver had to keep a thread there blocking and waiting for IOCTL response of disk filter driver.
So I want to know if my disk filter driver can send IOCTL on its own on initiative to my FS filter driver?
Another question is when I used FS filter to print out file name in IRP_MJ_READ/WRITE, there are something like this:
\Device\HardiskVolume1[-=Nested Operation=-]
Does this “Nested Operation” mean NTFS metafile from 0(FILE_$MFT) to 16?
Thanks.
