for files, no.  you get an error if you try to open
/dira/dirb/dirc/file/ .

for directories, _NO_.  when you try to open directory:

/dira//dirb/////dirc

you are, in effect, trying to open:

/dira/./dirb/././././dirc

and when you try to open directory:

/dira/dirb/dirc/

you are, in effect, trying to open:

/dira/dirb/dirc/.


namei, in reality doesn't "collapse" anything.  if it sees a trailing
/, or a / followed by another /, it knows that the pathname is
referring to the current directory (.) for the missing component, and
behaves accordingly.
