Essentially the uid_t to kuid_t and gid_t to kgid_t conversion.

These are the more complex filesystems. And I haven't yet had
the time to go through the preliminary patches in my development branch
and convert them into stupid obviously correct patches, or review them

The changes generally are pretty simple the amount of review to ensure I
didn't overlook things tends to proprotional to the size of the file

There is also the fact that I don't use most of those file-systems.

The big advantage of finishing those filesystems is that user namespaces
can be turned on in allyesconfig, allowing my compile time checks to
notice when someone doesn't use kuids and kgids.
