No documentation of what these represent (other than the cover letter).
I'd at least expect a comment of 'default creation mask for files' and
'default creation mask for directories'; it would also be nice to state
if the mask is positive or negative logic (compare the third argument
passed to open() which specifies bits to set, vs. the argument to umask
which specifies bits to keep clear).
Also, does this need a QAPI counterpart (or can you even create a 9pfs
device through QMP)?
