The create, lookup, and permission inode operations are all passed a
full nameidata. This is unfortunate because in nfsd and the mqueue
filesystem, we must instantiate a struct nameidata but cannot provide
all of the same information that a regular lookup would provide. The
unused fields take up space on the stack, but more importantly, it is
not obvious which fields have meaningful values and which don't, and so
things might easily break.
This patch introduces struct nameidata2 with only the fields that make
sense independent of an actual lookup, and uses that struct in those
places where a full nameidat is not needed.
