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

Hi,

2.6.26-rc4 seems to exhibit the following (new since at least 2.6.24)
warning when running find /proc/1:

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.

The other /proc/pid entries seem to have the same problem.
