wrong hardlink count in /proc

wrong hardlink count in /proc

[Dave Jones]

In 2.6.25, 'find /proc/ -name foo' will print out ..

find: WARNING: Hard link count is wrong for /proc/1: 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.

I also encountered this one. I think it is the one which 2.6.25.6 stable
patch 42/50 fixes.

Ah, great.   I just noticed that .26rc doesn't seem affected, so sounds good.
