mounted filesystem: procfs on /proc (local)

>Description:

When the "find" command is run on a "procfs" filesystem, error
messages such as these are output:

find /proc -fstype ufs -print
/proc/12403/file
find: /proc/12403/mem: Bad file descriptor

When the "-fstype ufs" options is removed the error messages disappear:

find /proc -print
/proc
/proc/curproc
/proc/12422
/proc/12422/file
/proc/12422/mem
/proc/12422/regs
/proc/12422/fpregs
/proc/12422/ctl
/proc/12422/status
/proc/12422/note
/proc/12422/notepg
/proc/12422/map
/proc/12422/etype

As a control test, the "-fstype ufs" option works correctly on /tmp:

find /tmp -fstype ufs -print
/tmp
/tmp/.X11-unix
/tmp/.X11-unix/X0
/tmp/.X0-lock
/tmp/p12263
/tmp/pf12263

>How-To-Repeat:

mount the proc filesystem on /proc
find /proc -fstype ufs -print  # produces error messages
find /proc -print              # produces no error messages
find /tmp  -fstype ufs -print  # produces no error messages
