--- Comment #3 from Keith White <kwhite@site.uottawa.ca> ---
Certainly not my intention to mislead with the bug subject!

I have no idea how to approach a fix.

Probably related to tmpfs reluctance to use VM: in order to use tmpfs as /t=
mp
and /usr/obj for a kernel build on a read-only RPI3, the previous patch add=
s a=20
vfs.tmpfs.inactive_percent sysctl that "allows" tmpfs to use X% of inactive
memory (default 0%).  Otherwise builds _may_ fail.
