[PATCH] procfs: Fix hardlink counts
The pid directories in /proc/ currently return the wrong hardlink count - 3, when there are actually 4 : ".", "..", "fd", and "task". This is easy to notice using find(1): cd /proc/<pid> find In the output, you'll see a message similar to: find: WARNING: Hard link count is wrong for .: this may be a bug in your filesystem driver. Automatically turning on find's -noleaf option. Earlier results may have failed to include directories that should have been searched. http://bugs.gentoo.org/show_bug.cgi?id=86031 I also noticed that CONFIG_SECURITY can add a 5th: attr, and performed a similar fix on the task directories too.
