Synopsis: namei cache unreliable for __getcwd()

Responsible-Changed-Why: 
I'm interested in these interactions with the name cache.

I think that the current purging of the name cache associated with
the moving/removal of a directory is probably unnecessary and the
real thing to do here may be to check the permessions in the kernel
code which does real path. I don't think it is possible for the name
cache to return out of date info though, it may just return info
which you might not be able to determine purely from userland.

	David.
