H A Dnamei.cdiff f6a4b4c9d07dda90c7c29dae96d6119ac6425dca Thu May 31 11:36:58 CDT 2018 Martin Brandenburg <martin@omnibond.com> orangefs: set i_size on new symlink

As long as a symlink inode remains in-core, the destination (and
therefore size) will not be re-fetched from the server, as it cannot
change. The original implementation of the attribute cache assumed that
setting the expiry time in the past was sufficient to cause a re-fetch
of all attributes on the next getattr. That does not work in this case.

The bug manifested itself as follows. When the command sequence

touch foo; ln -s foo bar; ls -l bar

is run, the output was

lrwxrwxrwx. 1 fedora fedora 4906 Apr 24 19:10 bar -> foo

However, after a re-mount, ls -l bar produces

lrwxrwxrwx. 1 fedora fedora 3 Apr 24 19:10 bar -> foo

After this commit, even before a re-mount, the output is

lrwxrwxrwx. 1 fedora fedora 3 Apr 24 19:10 bar -> foo
