VFS: Report file size for deleted files in /proc
It's useful to know how big deleted files are, in case a file system is filled up unexpectedly and the admin wants to track down which process is the culprit. This patch reports the file size in addition to (deleted) for /proc/*/fd links.
This modifies a public interface, but it's reasonable to assume that noone relies on the particular format here.
