IRP of type IRP_MJ_CREATE is responsible for opening of a file.
What is the FastIO routine responsible for opening a file?

2

FastIoQueryOpen.
It is used only in “get file information by name” syscalls, not for usual open.

Is it meant that file open will not be done in fast I/O path?

FastIoQueryOpen.
It is used only in “get file information by name” syscalls, not for usual open.

Yes. Only internal “query opens” in “get file information by name” syscalls.
