[K42-discussion] disable symlink caching patch

[Dilma DaSilva]

Hi Patrick,

I believe the proper way of doing what you need is to define a method
DirLinuxFSVolatile::readlink() with the behavior you need, i.e., no
caching of symlink value. I'm sorry that readlink was not properly
taken care of in DirLinuxFSVolatile; at some point we reimplemented
symlinks and we never did the proper thing for "volatile" file
systems. Could you please submit a new patch? Thank you very much!
