Seeing as how you aren't in a position to lay your hands on MVFS, I get to be
the bearer of bad news.
You'll have to recode this to do a retry loop, since MVFS rejects NtOpenFile
with access of 0, giving status 0xc0000022. The only question now is whether
you should do the READ_CONTROL first and retry to 0, or 0 first and
READ_CONTROL as the retry.

And of course, with 'df -T mvfs/file' now showing "unknown" instead of "mvfs",
you can imagine what else broke.
