If the existing proc instance has over-mounted areas, it can be impossible to mount a new /proc instance (look at SB_I_USERNS_VISIBLE for more details). Actually, runsc-gofer needs /proc just to open /proc/self/fd and to read a few generic files, so it doesn't need a proc instance of the target pid namespace.

runsc:gofer: don't mount a new proc instance
If the existing proc instance has over-mounted areas, it can be
impossible to mount a new /proc instance (look at SB_I_USERNS_VISIBLE
for more details).
Actually, runsc-gofer needs /proc just to open /proc/self/fd and to read
a few generic files, so it doesn't need a proc instance of the target
pid namespace.
Fixes #8205
