[PATCH] proc: link count fix
This patch fixes bug titled "sunrpc as module and bad proc/sys link count"
reported by Jiri Slaby.
The problem was, that only proc_dir_entry->nlink was updated and the
corresponding inode->i_nlink was not. The fix is to implement the
inode->getattr() method, and update i_nlink (if necessary).
A quick audit of proc code shows that no other attribute changes after
creation.
