IRP_MJ_ACQUIRE_FOR_SECTION_SYNCHRONIZATION comes with SyncType
CreateSection (or something like that). As far as I know, you don’t
need to createfile with any specific permissions to create a section
object. The CreateFileMapping docs detail what permissions you need to
create a section with the various mapping permissions.
Take a look at the last two emails I sent about MmCanTruncateFile (or
whatever it’s called, I’m working on three different things at the
moment). It seems to work, and nobody has told me I’m an idiot yet

Subject: [ntfsd] File mapping awareness from Create
Is there any way to do this. To know that a file is about to be file
mapped, or what create options/dispositions are incompatible with the
createfilemapping, so that I know, this kind of create will never allow
mapping to take place.
I know it is impossible to know for sure, but I need an app that is very
user interactive on the I/O side, so I would rather not wait for the
Modified Page Writer to flush data to disk, but synch the data just as
it is modified in memory.
Thanks.
